I had new Wharfedale speaker repair kits installed by Norm at Sertich Electronics. I had these speakers that had all the original drivers and they worked fine for a while. I had used Norm before for other projects and I know that he always said don't buy replacement speakers but I seen some from overseas in England and I just thought man I'll just pop these woofers in. They are four 10 inch woofers. Well, no don't do that just listen to people who do this stuff because from the beginning after I popped them in I knew that they lost presence mostly the lower end to them. I was down at Sertech and asked about the Wharfdale's and he said they had new kits that they have a rim on them before the surround. He said that's what Wharfdale is making now for those speakers. It took about two weeks for a complete repair, the cones, the center caps, which are large again and the spiders that he said were just loose. So I picked them up and popped them in and wow what a big difference you know I mean they sound so beautiful. They had lost a lot more than I thought by buying those replacements. I listen to all kinds of music most of it old music but wow everything sounds so wonderful Classical, blues, R&B, old hip-hop, old electronic music from the 80s when I was growing up I mean everything sounds great I mean wow. I knew not to buy replacements and I won't ever do that again but you know being so busy all the time I thought they'll just send them to my door. Now they are on the shelf and they are nothing to me now. I'm not sure what to do with them because I won't sell them I wouldn't do that to anybody. I can't believe I kept them that long. Now really music is what makes me feel good now. So thanks again to Sertech Electronics's. read more

Took a complicated amplifier to Norman at Sertech. Rather then turn me away because it was not anything he was familiar with Norman took the challenge to repair it. Unfortunately they couldn't get parts which was not their fault. But I give Sertech high marks for the effort. Be prepared to wait a bit for repairs as it is a small shop. But I will definitely use them again. read more

These guys were great at fixing a Dual CS5000 turntable and 2 Yamaha receivers (CR-1040 & CR-440), all audiophile equipment from the 70's, a few years ago. It is hard to find anyone to work on this kind of equipment. So, it is even better that Sertech are very knowledgeable, does excellent work, and are easy to work with. read more

I blew a woofer on one of my JBL Studio 530 speakers and took it in for repair. The repair price was reasonable and after moving my speakers around a bit I can't even tell which speaker was repaired! Good as new! read more

I am from Santa Cruz & after exhausting all the resources for stereo repair in the area, I got pointed to Sertech. Norman is the man. I have a stereo unit, over 40 years of age (1977) that needed to be brought back from the dead. The places in the Santa Cruz area were not cutting it. Reasonably priced & excellent service; very nice people at Sertech. There are also units that are for sale; nothing like the classic analogue units to bring that sound out from audio tape & vinyl. I highly recommend this business next to a hydroponic shop, not too far of a fetch of the Santa Cruz minded. read more

The technicians at SerTech are knowledgeable, experienced and provide excellent value for the services they provide, keeping vintage HiFi gear alive and healthy! If you are a vintage HiFi enthusiast and need your gear serviced, take it to SerTech! read more

Norm is the man. He will fix it good. Always comes through and always does the right thing. Easy to work with. Good communication. Keeps it simple. I have had him work on at least 10 different units in recent years. read more

No Customer Service whatsoever. Placed a call the first week of December and still have not heard back. Too bad there is not a zero rating!

Sertech knows vintage stereo equipment. Sertech repaired my Pioneer CTF750 cassette recorder. New belts & cleaning. Cassette player plays like new. Sertech is very busy because they do such great work. Just be patient & Sertech will repair your equipment back to new. Thanks Sertech!!! read more

A cool but VERY small hifi repair shop. I brought my vintage Sansui receiver there to have lamps, caps and to adjust the tuning cord. Norm (the owner) was very honest and clear about any work getting done, Bottom line; if you have the time to wait (nearly 4 weeks to even look at my receiver) there's not a better place in the South Bay to have your hifi gear serviced. read more

I entrusted my 40+ years-old KLH Classic Series CL-JR Loudspeakers to SerTech Electronics a couple of years ago and was astonished at the quality of the upgrade they performed. They replaced the failing parts and deteriorated gaskets, and now both speakers work As New! So this Spring of 2021 when my ONKYO Stereo Cassette Tape Deck ate five of my audio cassette tapes, I brought it in to SerTech. Norman and Bryan did an excellent high quality repair, again with the result being As New! I highly recommend SerTech Electronics for audio electronics repair. They are competent, professional, fair, and a pleasure to deal with. read more

They fixed my old B&O speakers and it works perfectly. Will definitely come back to this repair shop next time.

They took months to fix my equipment. Charged me upfront, never return my phone calls and rarely pick up the phone when I try to call. Update it's been 9 months and I still don't have my stuff. read more

I answered the question above about whether Sertech Electronics Repair can repair portable audio and I said that I'd post an update on my Lloyd's portable stereo (boombox) that I dropped off for repair. I got a call from Norm saying that he could get the replacement part and a few days later my Lloyd's PT-003 boombox was all ready for me to pick up. It works great and it's like new again. I'm actually listening to it as I type this. (Yelp won't let me post a follow up to my answer and cannot edit my answer so I'm posting an update here in my review.) The cost was just $40 for the repair plus the initial $85 diagnosis fee that was charged when I first dropped off my boombox. That was a bargain compared to other repair shops that I consulted. I was just happy that Norm would even work on my boombox since it's not the type of audio equipment that is cherished by audiophiles with deep pockets. It's good to know that Norm will work on all audio equipment, even things like my old boombox that are not exactly "audiophile quality" and only have sentimental value to their owners but absolutely no monetary value to audiophiles. He clearly stated that the only thing that would prevent him from working on my boombox was if replacement parts were not available. Thank goodness all that it needed was a standard off the shelf PC board component and Norm said that it was an easy fix. So if you're a fellow boombox collector like me, don't hesitate to give Norm a chance to make your old classic boombox play like it's 1985 again. read more

First class operation and fair prices by Norm You won't find anyone as good at electronics and vintage stereo repairs anywhere! One this planet! read more

I just called this place after calling many places to try to get my car amplifier fixed. The other places did not know of any place that can fix car amplifiers. The person who answered the phone here knew right away of a local place that can fix car amplifiers. Gave me the name of the place, he was very polite and seemed genuine in helping me get our car amplifier fixed. Thank you read more

What to do when your 30+-year-old audio equipment is on the blink? Go to Sertech! They are very knowledgeable and straight-shooters. How lucky we are to have them in Silicon Valley! read more

I don't generally like to give a review with this low a rating. However based on my personal experience I think two stars is a fair rating for this business. Let me start by saying that Norman, the gentleman who operates Sertech, is a very nice man and a real pleasure to talk with. He seems to be knowledgeable on all types of Hi Fi equipment as well. I am also fully aware that the equipment I brought in for repair is "vintage" and, perhaps not so easy to repair. However, I believe that Sertech's specialty is supposed to be the repair of vintage HiFI & stereo equipment. Among other things they also produce high quality stereo speakers and resale used/collectible equipment. At any rate here are some details of my experiences with Sertech: All three stereo components I took in for repair; a Mac 1900 stereo receiver, a Phillips GA 312 turntable and a Yamaha CR 620 receiver had to be returned to them for further repairs. In other words all three pieces were "come backs" for more repairs that could have and should have been diagnosed & completed the first time in the shop. I feel at the very least I should have been told, when I picked up and paid for the repairs, that there are still issues with how the units sound/play. Also I should have been offered a demo of the equipment to make sure it is working properly before taking it back home. Instead I trusted that they had completed the repairs and gave them "the benefit of the doubt". This was my mistake to be sure. After bringing the equipment home and hooking it up to play, it was very frustrating to find out the repairs had not been completed. It really makes me wonder if they even check their work before releasing the equipment back to the customer! By the way, on each of these components, the price for the repairs was no issue and they had instructions to "go through" everything to make sure all the functions/controls are working and sounding as they should. On the Yamaha receiver for example there are still "dirty pots" that make static noise when they are operated. This is after two stays at Sertech when they were supposed to do a complete check up on the unit and were specifically asked to clean and lube all the controls. On the Phillips turntable for example they had two attempts to repair the hum on the right channel. New RCA cables were even installed. Yet the hum still persist. and is in fact worse than before I took the table into them. Now instead of bringing the turntable into them for a third time I have decided to find another repair service that will hopefully resolve the problem (I plan to write a review of this other service after the turntable issue is resolved). Lastly I have found the communication from Sertech to be poor at best. Based on my experiences If one doesn't make an attempt to contact them, months can pass before one gets a call from them regarding the status of the repairs. The bottom line is I won't be going back to Sertech and will have to find another repair service that will hopefully get things right the first time around and provide a higher level of customer service. read more

Simply the best. I've had them fix dozens of my mistakes (yeah, I know...) and everything has always been just perfect. They don't get scared or tell me "it can't be fixed" when I bring them weird stuff, they just put their minds to it and make it happen. 10+ on the nerd scale, and I say that with awe and respect! read more

Experts. Lots of vintages there but they were able to take care of my more recent receiver and fix it at the right price. If you are in the hurry, it is not the place for you. Quality works takes time and requires passionate people. Norm is the man who has been in business for a long long time. Hard to find these kind of places these days. Will recommend to everyone. read more

I came in with a speaker that seemed hopeless. For the heck of it, he tried checking a small cheap component. What do you know, 10 minutes later my speaker was fixed. These gentlemen are wonderful at their job and are true engineers. read more

Go here for your repairs. I brought a mid-1970s Marantz 2230 receiver here to be fixed. It had several problems. They replaced all 6 transistors, all the lamps (lightbulbs), de-gummed the power button, and re-aligned the radio tuning wheel. This was my dad's receiver that he had my whole life, and it has never looked or worked this good; I'm really happy now. I felt the price charged was reasonable. It was $30 down for an analysis (you don't get that back per se, but they do credit that toward the final bill). The final bill was right at $200. It took them about a week to get around to doing the analysis, and just another day to do the fix. They seem to get a lot of business here and I guess are constantly full of units to fix. Another review mentioned that you should call them to check up. I would recommend that too, but make sure to give a respectable amount of time before calling (if he says 8 days, give him a full 8 days before calling). read more

I called them to see if they can fix my Car Audio speaker, they said they weren't sure, so I offered to send email with pictures of the speaker. They did not call me back. So I called back telling them i sent them Email, the guy tells me they will get back to me. Nobody responded to me ever after. I'm not wasting my time calling them 3times for the same thing. read more

This is my go to place for vintage (60's -80's) hifi repair. Norman is passionate about fixing these units. They are professional and good at tackling hard to fix issues in rare pieces. I would not hesitate to take hifi units there for an inspection. read more

Well, the gentleman helping Norman should be selling used cars. Nothing worse than a guy who treats people like they are fools. Norman, is not transparent. Charged 200.00 to clean my tape heads. read more

Robert the lead tech is fantastic at fixing anything. Few people knew he builds his own custom made speakers-cheaper than the big guys, and so good, they will blast you out of the building, He also sets up stereo systems, and even lighting systems and does a great job. I have used him for both. He can fix anything, and is reliable and fairly priced. If you love good sound systems, this small, but professionally awesome place will set one up for you cheaper than other quotes I received read more

The SME Norman repaired my Mcintosh tube amp in weeks and fixed some inherent issues probably from the 60's. It works and sounds great now. Cost is reasonable. One thing worth mentioning is that you do have to call to check the status, and that he does not perform / charge for unnecessary repairs! I got a few more pieces to go too. read more

They fixed my ancient Harmon Kardon receiver at a reasonable price and right on schedule. I found them using Yelp and ignored the few reviews that complained about delivery time ... I found their estimates on delivery very reasonable for this type of work. If you have old stereo equipment and want honest, reasonable repair go here! read more

AWESOME speaker repair. Recently, I was given a pair of JBL speakers. I lusted for these very same speakers back when I was in college. When I got them, these JBL's were abused and I mean ABUSED. The woofers were kicked in and the tweeters and mids were blown. The speakers were Toast. The cabinets were scratched and blasted. They were basically a throw away. Norm fixed everything and now they look and play like new. The grilles were missing when I got them and Norm built new grilles for them! The best part of all was Norm's price was darn right CHEAP! I won't go anywhere else! read more

Got my 30 year old Nakamichi receiver cleaned-up and tuned-up by Stretch. They did a great job and my only gripe is they were so busy that they never called me to let me know my receiver was ready for pick-up. They said they were backed-up with jobs when I dropped-off my receiver, and it will take 5 weeks before they can even start the repair job. But I never heard back from them so I gave them a call, then they could not find my receiver so I had to wait for them to call back. These guys are super busy and it will take awhile to get your equipment repaired, but I was pleased they revived my Nakamichi and got it running again, and the repair was not too expensive. read more

I brought my Pioneer SX-1250 in to Sertech for a complete overhaul. The results were amazing and better than I expected. Sonically the amplifier is better than new and they were able to completely fix what minor damage had occurred over the years. Norm and Robert are very knowledgeable about the old analog receivers and other stereo components. They are doing a great job keeping them alive. Great service and quality work. The best place to go for stereo equipment repair! read more

Nice friendly store. Very knowledgeable about all things electronic. Took my amp/receiver in for diagnostic at $79 (fair price). Turned out was a minor issue - everything's good now! read more

Wow, I've read some of these reviews and wonder if this is the same shop. Yes, it is. However I have nothing good to say. My JBL speaker has been at Sertech for 6 months for an alleged amplifier. Took over 3 months to get it diagnosed. 3 more months to find out it needed something in addition too or instead of an amplifier. Still waiting with absolutely no communication from them unless we called inquiring for a status. 6+ months with half a sound system... do they care about customers? We will never use them again, instead I'll take my repairs all the way to SF. Seems to me the shop is a hobby, not a job. The system made me select a star, but no stars from me. read more

Was recommended by an A/V store in Saratoga and made the slight trek out to Sertech. Long story short, it took a while to diagnose the problem, because my unit was from overseas and required 220v, but once WE (I had to call 3 times until we uncovered this nuance) it was fixed within a day. "Stormin'" Norman and his crew of audiophile techs are really good at what they do but like all techies, they take a bit of pushing to get the job done. Although I recognize they have a big queue. In the end, I'm happy with the service and recommend them to anyone that needs to bring an old/broken audio unit back to life. I'm glad to have my surround back in the living room. read more

Had a good experience. He is busy so it may take a few weeks but the job will be done right at a fair price.

Robert installed a home theater system for me and Norman did the follow-up to make it sound perfect. Highly recommend this unpretentious, friendly place. read more

I agree completely with the other 5 star reviewers - Norm is simply the best I've seen when it comes to consumer electronics diagnosis and repair. He is insightful, vastly experienced, honest, and supremely competent. Altogether a great guy to work with. But like the managerial truism, if you want something done, give it to your busiest person. His shop usually has a long backlog, especially around the holidays. He focuses on getting the job done and will call when done but don't expect him to hound you for pickup. The few complaints you'll find here are probably the results of some the assistants he's had through his shop in the past. He will also make house calls and his shop devotes some space to consignment sales. Note that he has recently changed his diagnosis/ pre-payment fee from $30 to $100, which seems fair to me. read more

Our TV broke and Samsung recommended this company and technician Frank to assess damage and possible repair for our insurance claim. These guys are very solid in their knowledge, and pleasant to work with. Highly recommend. read more

Called Norm to get an estimate on fixing some Sony ES audio equipment. He was very helpful and told me to bring the units over. I had bought both these units back in 1998 when I was setting up my home entertainment system. It was more a sentimental need since the DVD and cassette deck have been with my wife and I since we got married and our kids grew up with the 5 disc DVD player. Dropped the units back in early October (Norm is busy and told me it would be at least 6 weeks), and waited patiently. Norm called today to say both units were ready. Picked the units up and am happy with the results. We are lucky to have people like Norm in the Bay area. In a throw away society, it nice to have someone who still repairs electronic devices. read more
