Have you ever seen a power supply without any capacitors ?
;-)
(Just joking of course.)
Most of the e-caps in them Funia units, that go bad, are the ones tied to
the inputs, and outputs of the +5, and or +6 volt regulator ICs.
470ufd.@10volts
rings a bell, but, check all that apply. Might try replacing IC670
(LM7806)., and check solder on Relay 601.
