Audio hum fix for Wurlitzer Model 3000 jukebox?

This is not old enough to be vacuum tube based (at least I am pretty
sure it isn't) so it must surely just need new electrolytics as it is
30-40 years old and on original parts. The hum was quite and over the
past year or so has become intolerable to the point the box is
unuseable. Surely somebody knows exactly which caps to replace (or at
leasts knows where I can go to find somebody who knows this), right?
Help me out, please?

A few minutes with Google showed me that this is of about 1966 vintage and
(surprisingly) is all solid state.

Anyway if it had tubes wouldn't you notice that it had to warm up?

Probably not, because with tube type amps, the juke box manufacturers kept
the filaments on all the time, just enabled the B+when the record was
selected. Voila - instant on.

Replace the electrolytic capacitors....we have service manuals available for
that model for sale.
Kits are available from www.verntisdale.com and I think he has schematics up
on his web site.
