Hi.
Anyone got a scematic for this excellent Sub amplifier?
I have No sound, relay do not turn on, No voltage to relay. No DC on output either. All opamps looks ok when tested separately.

Let's see how this goes, it could be worth a try moving to the amplifier subforum. What can you tell us about it?
Maybe you are right, but this amplifier is a part of an subwoofer from Audio Physics called Rhea.
Found short between collector-emitter on this BF417. I have 2 amps of this type and both are same, with same short. Could this be a normal case? Shorted?
Both amp have fault and do not work, found No other signs. Changed all caps to be sure they are ok. Any advice would be Great. Do not know if any other recognice this behavior?

Transistor i found shorted was shorted in pcb layout so this is not a fault, but normal.
I Will provide solution here, if i get it back to working condition.

What is the symptom of your faulty amp? Is it Just without any sound, No rele click when turnéd on?
Or is there some components burned eg?

No sound, the relé is not clicking, no smok/burned parts.
No measurements has been done, as far I know
