Sheldon, is a total pro and very knowledgeable. He is also very honest. I love my 1978 Concept 3.5 receiver he sold me. Don't just drop anything off with him and expect fast repairs. He does complete work and doesn't rush jobs. We are extremely lucky to have a repair person like him in the East Bay!
Sheldon is the best! I'm so grateful to have someone like him in the Bay with all of his knowledge, expertise and dedication to his craft. He is genuine, thorough, and will walk you through his process so that you can gain insight into your analog equipment. I bought some used Technics SL-1200s on ebay that needed servicing and he did a great job. I now have fantastic turntables that will hopefully last me a very long time. Thank you Sheldon!
Sheldon is the best technician I've ever used and the only person to take your pieces to. He takes his time to properly address the unit. His pricing is absolutely fair and he will always be straight forward with you. He's repaired my Accuphase and Yamaha units but has experience with all
I brought in my vintage turntable with a frozen height adjustment, and the technician did an excellent job bringing it back to life. They also replaced the old RCA cable and fully serviced the unit. Extremely knowledgeable, detailed, and thorough—a true professional who clearly knows vintage audio inside and out. The turnaround was fast for a mechanical repair, and the turntable now runs perfectly. Highly recommend for anyone who cares about quality audio gear and wants it done right!
Sheldon is amazing. My 1974-era Yamaha CR-600 amplifier gave up the ghost so off to Champlifier it went. It took some time to land an appointment but it was worth the three-month wait. Sheldon takes obvious pride in his work and truly cares about the entire customer experience. He sets clear expectations with regards to cost and duration. When the job is done he is meticulous about following up to ensure satisfaction. Note that Champlifier's services don't come cheap, but the high-quality of service is worth the premium. I could not be more pleased with Champlifier.
