38-39 Vibrator Power Supply Replacement
07-20-2017, 04:50 AM
I've decided to try and use the existing vibrator to supply the B+. I recapped it and it's working, providing about +125V. However, it's very dirty, injecting a strong hum and overrides any signal. On the scope, it looks similar to a square wave. I've installed new electrolytic filter caps and temporarily added more capacitance, but this noise persists. What could be causing this?
