This guy knows his stuff. I knew it the second I walked into his shop. Some people just give off a…read moregood vibe. I have newer - u-turn audio - turn table that wasn't producing sound out of the left speaker. Not usually the kind of thing he works on, but Dr. Dan agreed to check it out anyway. I spent about an hour with him in his shop, surrounded by pugs, chopping it up sharing stories, while he troubleshooted the issue. After a few tests, he figured out what was happening, recommended I buy a $20 preamp to fix it, then sent me on my way with a handshake and a smile. It was quite the enjoyable experience. You can tell he cares about what he does, that he takes pride in his work, and is extremely knowledgeable when it comes to vintage audio equipment. *He's also a man that enjoys a good story, so if you have one, come prepared to share.* I personally value vinyl. It's a beautiful analogue tech that produces sound using magnets and emf's translated from a needle cruising on plastic. It's crazy to me that someone had the idea for it, let alone that it actually works. Yet it remains. Not for the nostalgia or efficiency; but for the warmth of the sound, for the collectibility and sense of ownership, for the love of music. I was looking for someone who held a similar sentiment. You wouldn't want someone who hates cars to be your mechanic. I decided to call Dr. Dan after reading some reviews, in which pretty much everyone suggests he the best. To that point, all I can say is, they were all right.

Discussed over the phone, took it back, he had it for some time and at one point told me it was too much for him and he is not a reel to reel expert. Well then why wouldn't you tell me this in the beginning? lol Took it to another shop down in the springs highly regarded for reel to reel repairs. They looked at it, seen parts that were supposed to be replaced by Dan in fact were not and appeared used. Called Dan, he decided to berate me like another neg review on here, then decided to harass me by calling me every day for a few weeks to berate me. I had to block him, he still left messages. And he still kept my money despite my doing any work and then using used parts. Horrible business and lesson learned.

For a low flat rate, he will give an estimate and apply that service fee toward the repair. If he can't repair it, he will use the fee to recycle the TV for less than the cost to you to recycle it ($150+). It's now illegal to throw out a tv anyway. A win-win for this frugal gal who hates our throw-away culture!

What I really liked was the fact that he gave me a day that my phone would be done and even though he had a lot of phones to work on that day he stayed working past closing time to make sure I got my phone back the same day he said I would. A little later but I appreciated the fact that he stayed working after hours to make sure it was done. The quality of work was excellent and I'm happy with the service and the product. I highly recommend this business.

I sold most of my gear, but took some of my favorite pieces of equipment home to build a high-quality studio for myself and some of my diehard customers. A few of my favorite analog units had died over the years, but I held onto them in hopes that someday I would find an individual that could repair them...even after several unsuccessful attempts by other repair shops. A friend of mine had always raved about this fellow named Ross, that he takes all of his equipment to. After being disappointed by the attempts of so many other repairman, I was skeptical, but decided to take a chance... and I'm so glad I did! Everything he has repaired for me works flawlessly. He meticulously checks every solder joint and component to make sure that each piece of equipment meets or exceeds factory specs. And...his pricing is extremely reasonable! And to top it off ...he is one hell of a nice guy and a real man of integrity! I dread the day this man retires!
