Hi All;
The other night I took out my DC Simpson Meter that does 0-15 Volts DC, and along with it, in the same metalbox was a couple of Switcher Power supplies, that I didn't know that I had.. The Meter is to monitor my Filament voltage.. Which is set to 1.8 Volts..
One was for 2.0 Volts DC and the other one was for + / - 12 Volts DC, so with a set of resistor dividers.. I now have +/- 3 Volts and +/- 7 Volts DC and all very regulated and smooth..
I put a couple of Caps on my 137 Volt B+ line and hooked up the Speaker and my Audio Signal Generator, and the Audio Amplifier works just like its susposed to, I even looked at the Signal with my scope to the Speaker terminals.. It puts out nice Sine waves..
Before I had mostly 60 Cycle Hum, very zagged, and barely there..
THANK YOU Marty
