I can use the schematic of the 5G9 tremolux or princeton also with an amplifier with 4x6L6?

thanks

I completed my tremolo (bias modulating type), now how do I set the bias?
28mA with trem. off is o too much low?

anyone can tell me if there is a procedure? I have a oscilloscope and dmm on my bench.

Thanks

Just disable the tremolo while setting the bias as you would with a non-trem amp. You will probably have to compromise between 'optimal' biasing and strong tremolo because changing the bias affects the effectiveness of the tremolo effect.
