It’s been a few years since I stepped away from electronics repair, but I’m excited to announce that Retrovoltage is once again back in action and working on projects. I don’t expect to take direct customer work any time soon but am teaming up with a local furniture restorer to extend her business to include vintage speakers and console stereo equipment. I also have a handful of projects which I’ve kept since I last posted and am finally ready to tackle!

I kept a few pieces of gear from the old shop, including the variable power supplies and isolation transformers, the soldering equipment, stereo dummy load, AM/FM alignment generator, and GPSDO. The counter, oscilloscopes, signal generator, multimeters, and Audio Precision stack with external variable filtre are all new.

With the center vents, I can technically have two projects going at once on the left and right side of the bench. I’m looking forward to getting to work!

My first project was a repair and evaluation of a DBX SFC-10 Soundfield Imaging Controller, which I’ll post about later. Currently working on a KLH Model 25 which had some dubious quality work done in the past that I’m sorting through.

In any case, look for the next installment in days or weeks, not years!
