twin bias
Any one try to cathode bias a twin with a single resistor?

Re: twin bias
The nearest I have seen to that is the 80W Budda amp. I think it was a 50W resistor, I could be wrong. Might have been 80W. Cathode to ground voltage is way less than plate or screen.

Re: twin bias
I had forgotten about budda's, did some work in one some years back.
I remember it was a pcb with the power side hand wired, over rated cathode resistor.
50w sounds like I remember. At worst, 140w at 470v is around 1/3 of a amp.
25w is well shy of twice the watts of that much current at bias voltages.
