I Love Vintage Analog Synths Ive Built a Couple

8th Jan 2017 analog oberheim vintagesynths

I love vintage analog synths! I’ve built a couple modules from the late great Ray Wilson and have dabbled with others. A classic happened across my lab bench recently, a classic from the great Tom Oberheim, a TVS-1. It is in good physical shape, but not functioning at all. Thanks to the schematics at Ersatz Planet I’m pretty sure I can get this baby working, and maybe expand with some homebuilt modules!

Problem List:

1. No -15V power

2. No Sound

3. Lower E on keyboard not triggering

4. No CV1 output from keyboard
