Hi i'm a newbie in diyaudio, how and where to measure the quiescent current when adjusting the bias pot?
thanks

My amp doesn't work... 0V across fuses/10ohm resistors, 36V between + & - fuse clips, no smoke, no transistor heatups when adjusting bias pot, variable dc offset when no output load, but the speaker pops when connecting to output terminal... what could be the problem? does the driver transistors sensistive to heat? I think I overheated them when I soldered it to the pcb...
Thanks!
Thanks!
yup, i connected the input and output gnd to psu to gnd ground[/QUOTE]
Picture not clear, but your soldering don't look good.

Ok i'll just try again... will it sound good even if I use ceramic and mylar caps?

Does it sound better than a gainclone even if i use ceramic and mylar caps?

No, this PSU is with soft start for main transformer and separate protections for each channel.
CAn hv350 be used with sanken 2sc2922-2sa1216 or mjl21193/94, if yes any changes
I want the amp to sound good , but i need more power, which pcb should i use , ax-14 uses just single pair, i dont want to compromise on sound quality.
I completed my tower speakers, installed crossevers, connected to amp,
Result-Bass is good but seems a bit boomy, Mids and highs are not clear dont sound in ratio to lows.
Could this be due to amp . I got this kit and assembled it. Pls check

HV350 is MOSFET amplifier, BJTs can't be used, I suggest B500 or SR200 from http://www.diyaudio.com/forums/solid-state/173462-studio-reference-amplifier-4.html post #35, but I not made DIY version pcb jet.
