    Is it necessary to recap the PSU (Sony)?

    FWIW I opened a Sony PSU two months ago and it was positively oily with cap goo with puffy caps. At minimum, inspection should always be done before plugging one in that is new-to-you or has been sitting idle for a while. And make sure you know what leakage looks like. This forum is full of...

    A better keyboard for the duo series would be a godsend. Even when they work those keyboards are awful. When my Duo 250 was new, I had to replace the keyboard twice out of warranty from some parts vendor advertising in the back of MacUser magazine when unimportant keys like N and Space stopped...

    Problems with Quadra 610 ; Dead Board and Unusual PSU

    Take lots of photos of the PSU before you take it apart (make sure good lighting, focus, etc) and as you remove components make sure you know where everything came from. I create a grid system with a plastic small parts bin and document which slot (C10, etc.) each component came from and put it...

    IIci won’t stay on

    It's hard to tell from the photos, but any sign of green (cap juice corrosion) or dust you cannot blow away with canned air (which is therefore stuck on with cap juice) is a sign of bad caps. It can be subtle or quite spectacular--you may have a more subtle variety...

    Apple 2e card error

    Have you tried putting the card that worked back into the LCII to confirm that something on the motherboard side didn't break? Also check the pinouts of each board if you can find them online. Most cards don't use all the pins or use them differently, which could point you to a pin socket on the...

    Classic II analog board corrosion--help?

    Thanks all. I’m going to try to repair. Watching some of Branchus Creations videos there have been worse looking boards brought to life. Will report back.

    Classic II analog board corrosion--help?

    My Classic II analog board had some really nasty electrolyte corrosion. It was non functional, and after recap a lot of solder mask just came off with an IPA wash. At least one pin (a resistor) has lost all the copper down to the fiberglass and needs to be bodged. And a large area where the...

    @zigzagjoe LMK if you do not have any pictures of "greenscale" and I will attempt it :-) I have to open my red mac anyway to add a PRAM battery extender.
