Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: starved filaments

If I get around to trying this idea, I will post the FFT findings here.

I noticed that there seems to be a lot of 60 & 120 cycle energy in my
SE DC 2A3 stereo circuit on the FFT. About -60dB from the fundamental.

It needs to be a bit better than that, so I got to redesign or go back to a one channel/mono circuit.

Always a problem with something.
