Tantral OD Bias

[stevtron]

What is the best bias (drain) voltage for the J201's ? I have it around 4 V and it sounds ok for me.
How is it in the real one ?

Normally 4.5v is standard...but by ear is fine. I think the factory setting was around 6v.

Nice , I'll correct that … thanx

OK, done … but it makes no difference, not really . So, everything is fine !

What voltages are you getting on the drains of your mosfets?

 

[Nostradoomus]

Should be somewhere near 7.45 on drain and 2.45 on source

I don't know, but it's perfect now ... thanx for your help !
