Re: M-audio AV30 speakers recap and repair

The zeners should 15v, I replaced with 1N5352 5W, Originals are 1W. I also replaced the 2 220uf caps, repaired the power connector and installed sockets for the 4558 and TL074 and replaced the ICs. None of this fixed the problem. I read that the 22uf cap, C13 that you can see in the above pic is the issue. I replaced both of those along the edge of the pcb with 10uf and it is working.

ymmv,
