I wouldn't have a clue how to fix them, I never took those valuable electronics courses when I was younger, now who has the time?
You might be surprised at how much money a little "DIY self-taught crash course" can save you, in terms of 1) no repair costs for busted gear, and 2) no new cable charges for busted cables. Don't laugh, cables are reeeeeaaaally expensive.
Anyway the multimeter is your friend.

Continuity (resistance) checks at the inputs and outputs are a good place to start. It would definitely require patience, and in the end might not get you a working Wurlitzer or EIII. But it can be lots of fun. Seriously.
(Just don't touch those little cylinders and circles. Capacitors are nasty little suckers...)
A few Wurlitzer schematics
One of the things I hate about contemporary gear is the lack of decent schematics. I couldn't find any for the EIII. However
the manual does mention something about recalibrating a volume slider or something...
Anyway this is coming from a guy who can't fix his own microphones.

So take my suggestions with a big grain of salt!
Cheers,
