Make your Dynaco Stereo 120 Power Amplifier Better than New with these Kits
You can bring your Dynaco Stereo 120 Power Amplifier back to life. Even if it’s working, you can make it sound better than it ever sounded. You can feel the great feeling of accomplishment that comes from building a kit…You begin with a collection of quality parts, and end with something that sounds great, looks great, and works great. And you built it!
The Dynaco Stereo 120 Power Amp was revolutionary when it came out in the mid 1960’s. It had some problems, though, mostly related to under-biasing of the output stage. The result was the cross-over distortion that came to be the unpleasant hallmark of “transistor” sound. Forty years of progress later, we can do a lot better. With our kit, you recycle and reuse the highest quality, timeless parts of the Stereo 120, and replace the parts, e.g. the amplifier and power supply regulator modules, where technology has made the most improvements.
