Yeah, TH is heater supply. I assumed it was ok and moved on.
Now, however, I have no voltage drop at all across R10L (and R10R). Both ends are reading -14,98V. The only thing I got with the search function was someone who had Q6 and Q7 installed wrong way. Mine are text-side to front which is correct I guess. However, when I test those BD139s, I get 0,62v B-E AND E-B. Are my transistors fried or what could be the problem?
Argh, I'm going to have to unscrew the board again.
Only took half an hour to do it last time since my standoff isn't exactly the right height and my solution isn't very easy to implement :D
Wow, I guess I'd give up now too if I had a descent amp, but I broke my last amps pcb while modding it. I think I'm going to replace the BD139s unless someone has a better idea. I really hope my SOHA II won't take as long to complete as yours :D
