Hi Apex,
Question 1: I can change 2n5551 for BC546 ?
Question 2: I can test the amplifier with only 2 IRFP240 and 2 IRFP9240 ?
I think so...
Thank´s !

1: Yes, but reverse pin layout EBC>CBE
2: Yes, for test, but BIAS must be adjust again when add 2 pairs
Apex, The CLIP LED resistor layout is different from the resistor layout is 6.8k or 10K?
Thank you !
Thank you !
Apex Hi, I power on the HV350 and the sound is coming out distorted, I think it can be ceramic capacitors of transistors drivers 100PF ... What's happening? So I can send you the photos.
I think bias is to low, use 10R resistors series in rail and set bias to get abot 2V on 10R resistor. Post pictures here.
Regards
Apex, this voltage is only test... Now I'm on my work (informatica) when I get home, I check this problem in HV350.
Thank you !
Thank you !
Ok, I use fets from many factorys IR, Fairchild, Haris... and gate voltage for bias is very diferent 2,5-3,5V (5-7V gate to gate), but that can be easy set by change 470R in base to colector of 2N5551 (BC546).

Apex,
Question 1: the Zeners is 15v right ?
Question 2: the input capacitor is 1mf non polarized, but i used polarized...
Thank you.

Thank you.
1: Zeners are 15V
2: Polarized capacitor on input can't cause any distorsion
Do you use BC337 and BC327 in VI limiter?
