Commodore 64C,
so should I just chuck the whole thing and use a Commodore
emulator because I'm unworthy of grace due to the fact I didn't like the
original unreliable 64 brick?
Hmm... IIRC the C64 brick is potted, and almost impossible to repair.
Unlike the C128 brick, which is trivial to open, and not hard to repair
(I've had mine apart).
I think what I'd want to do in that case would be to build a replacement
PSU that followed the design of the Commodore one as closely as
possible, but which was repairable, and used generously-rated components
so it was more reliable. But I would not want to replace the whole thing
with a switcher, which is totally non-original.
You could get a third-party replacement C64 PSU which was a switcher.
No, I don't know how they did the 12V AC line.
They were incredibly reliable, ran very cool, and a fraction of the
weight of the originals.
Gordon.
