Problems with Quadra 610 ; Dead Board and Unusual PSU

[jazzius]

Im working on my centris 610, just got to the TDK power supply, I havent edited the pictures or measured the caps to add to caps.wiki yet; regardless here is the list of values and locations from mine:

I didn't notice you posted this until now, but I appreciate the help with tracking down the cap values!

Unfortunately, I will have to come back around to recapping my Quadra 610's PSU later, as the board suffered a lot of leakage damage, and it's possible I lost the PCB itself and the IOSB chip in the process, so it may be a while until I come back around to getting my Quadra 610 back up.

It's likely I will have to rework the PCB from scratch, or more likely, I will use my board as a parts board to fix another Quadra 610 with different issues if I can find one at a reasonable price.

I tried using 30AWG Kynar to bond the IOSB back to the traces, but the work was far too small, and many of the IOSB's legs broke in the process, so it was too far corroded and too delicate to begin with anyhow.

That IOSB chip is a nightmare. I was able to life it on my Q610 LB (with great care and tons of ChipQuik). I ran some bodge wires (I use 32AWG magnet wire) to what remained of the legs. Felt like surgery, ultimately wasn’t successful. Now the board is in my parts bin.
