Hi,

I have a Mosfet Power Amp, using a single pair of J49 and K134 devices. Is
there a standard bias voltage I should adjust to, or is it design dependent?

Thanks,


Gareth.

If you set the current at 100mA then for sure it will be ok. Once I made an
amplifier with the J50 & K135 Mosfets with a bias current of 100mA, and it
worked fine.
