Colin,

I asked one of the best Apple II (and Mac) hardware gurus I know
(Harold Hislop) and he stated:

The power supply is failing (Likely a failing filter capacitor on the
+5 output line). (not too hard to fix, but dangerous (ALL switching
power supplies can be dangerous to work on))

Hope this might help you.

Best regards,

Ulrich
