I recently acquired a 128k to finish off my compact collection. It has some obvious power issues - screen wobbles and moves with the floppy drive access.

I opened it up today and the board has the number 820-0082-B 1983 on it - looking at Console5 and the internet in general I don't see any cap guides or kits out there (of course I just put a mouser order in yesterday)

Is there a guide/kit out there or will I be making one in this thread? :)

pretty sure that's the part number for the bare circuit board. you need the number on the other side of the Analog Board, forward edge near the top, 630-0102- , the Assembly part number. it's hard to see with the board installed.

BUT, Console5 only has the one kit (well 2, 1 US & 1 international) for 128k thru Plus (and read the notes):

Yep! Just ordered the kit. Been so long since I opened it up and it looked like a part number i just assumed. Thanks!
