Haha

Very good point. Harleys are a piece of junk and need pulling apart and servicing on a daily basis.
Firstwatt amps last years without any servicing.

I'm thinking about full JFET Babelfish based on UJN1208K depletion mode output devices. What do you think about it ? Can I disconnect actual bias circuit and bias output transistors from outside negative PS ? Where R27 need to be connected after removing red marked parts ?

that would be completely different amp , which I can't recommend that you make , if you are not equipped to set and finish appropriately

if you insist , open dedicated thread and we can help , but be prepared for workload

Zen, I have scope with FFT, laboratory +/- PS, so I can limit the current during regulation in new bias circuit and adjust properly gate resistor. Ok, new thread here: Babelfish JFET with UJN1208K

I have two PSU from two Aleph 2 mono-blocks.
Is it possible to do with the Babelfish PCB a similar to Aleph 2 amplifier?
What changes should be made?
Thank you.
