Percision Audio Labs in St. Louis, MO just did excellent work on a 35 year old preamp for me. They are authorized for Yamaha.
Reputable restorer for vintage integrated amp
Just purchased (but have not yet received) a Yamaha A-960 integrated amp. Should be here sometime next week. I bought it because of its great phono amp section and plan to use it for that purpose only. Owner says it had light use. But on further research I saw posted here in an old thread that this particular amp has a problem with capacitor failure which could result in a fire. Before putting it to use I'd like to have a reputable tech restore it to upgraded, safe levels. I live in the greater Kansas City, Missouri area and have used a local guy in the past (but it took him months to reset my power amp after I carelessly let the left and right speaker plugs touch and short the amp). From what I understand all he did was put in a reset code. I wouldn't mind shipping the Yamaha amp off. I just don't want to be waiting for more than 2 or 3 months to get it back.
Anyone had their vintage components worked on and loved (or hated) it? I'd love to hear about your experience (the good, bad and ugly). Thanks in advance for all the recommendations.

Stereo Rehab in Chicago. Reliable and honest evaluation prior to committing any $$$. Reasonable and fairly quick turnaround. Unfortunately a long haul from KC. Not sure if you could ship to them but it may be worth a phone call. https://stereorehab.wordpress.com/ |
