[SOLVED] +15V DC in the CV

[BastoonVaulav]

Hi everybody,

I was testing a module and very unfortunately, the cv output of my x0xb0x touched the +15V of the module, the x0x was working perfectly before and now I have no sound.
I swap all the IC near J6 (IC9, IC11, IC12) even IC23 because it was getting to hot, but no changes.
When I mesure at J4 i got the 5,33V okay but the 11,8v drops, but if J4 is not plugged to the main board, it stays at 11,8v, so assume the problem is on the main board.
Maybe I should change Q26, because it's one of the first transistor after J6.
Any suggestions?

Thanks in advance

you could try replacing D31..

Hi antto,

thanks for your answer, I just changed d31 with another 1N4148 but no changes, still no sound.
Maybe i should try to replace d30 which is just next d31, or i shoud look elsewhere?

I just changed d30 and it works now! I don't know if it was the one that was faulty in the first place or if I overheated it while desoldering/soldering d31.
Anyway thanks again, I can get back to acid now.

Cheers!
