- Hmm. Last time I checked most C-64s have non-servicable epoxy-potted
- supplies. There ain't a blooming think you can do to fix them short of
- cutting them open with a hacksaw and chunking into the epoxy with a
- chisel. The potting also helps keep them excessively hot and burns up
- the potted 5V regulator faster.

- Are we talking the original lame-brained Commodore part or one of the
- improved repairable third-party power supplies? I don't know what the
- current price is, but at one time Commodore was asking something like
- $50 for a replacement. Talk about excessive heat!
-
- So why didn't you guys designed the C-64 PS to be servicable to begin
- with? Why the epoxy potting? Are you that hard up for revenue that you
- have to design a supply that's bound to fail, then charge excessive $$$
- to replace it?
