Sounds good, i ll try to make a bom at either digikey or mouser with either nichicon and/or panasonic caps since they are pretty common.
Cart export from Mouser attached all nichicon caps, correct size/values. If someone wants to take a look and double check please.

@xtrasmiley I moved all dips to On to get into test mode. Then I reset the defaults, I think it was the first option. Works now
would totally appreciate that. My audio sounds like crud so I’m definitely going to recap
Could you snap a closer photo of VR1 in the middle of the pcb? Mine is a 102 trimmer, but yours are fixed values.
Added mouser cart export on post above.
Pic of manual attached - shows vr1 with no indication, but it seems to be for contrast adjustment, I guess they removed it and placed a couple of resistors in my revision.
Also check your volume wheel, i found this, looks like at some point the MBs volume pots were reflowed or replaced. Can you check yours? I also have audio issues, scratchy, dropouts, if you find a replacement for the volume pot let me know.

Just double-checked by ordering it... i'll let you know when it shows up
Yeah my joints there look poor, I’ll reflow them. The backside is better. https://imgur.com/a/reHRHE1
looks rough, you might need a whole new volume pot, if you find a match let us know, I would like to just replace it altogether with a new one or a better one if I can. Thanks.
Oh man. Thanks for pointing out the contrast pot. Things look much better now.
I too am in scratchy audio land. Going to follow suit with you guys on recapping and reflowing the volume pot.

hmm....I might have to add that pot in the future, can you guys take pic/part number.
I think in my revisions they removed it and added fixed resistors. But I will recap first to see how things improve.

Thanks, i think i wont need it but the option to adjust it would have been nice even if not needed.
lmao, yeah, ive been meaning too. So much stuff to add/remove. Time I change the sig too, maybe.
Somebody needs to update his multi list, slacker!
That looks like the board I already recapped. They all blueish Nichicon UKA and/or UKT series?
@Frank_fjs
Some pics of Brizzo's multi cart.
Maybe you can adapt your oled selector board to have pogo pins/etc.. to go over the switch pins solder spots? The switch is nice quality/feels solid so if we can leave it in place that would be nice, and would make for an easier install of the selector.
I take it you need 5v/gnd/reset lines, so heres a couple of locations I found that should be suitable in case you wanna take a look see

Can I use those 2 pics on the crystal system section of my site?
