So I've been having fun going over this 33, trying to follow the schematics
I've found. Still like visiting an alien world but, I did manage to get the

I've tested the caps and they seem to come back oka

I see you didn't bother to check the clutches. You'd have found that the
clutch that reset the keyboard could be released.
The buzzing may also be related to your fuse blowing the supply
that feeds the receiving coil may h

If you put a clothes pin as this photo shows, does the buzzing go away?

Well, that fuse must have been carrying current in order to blow. And yet
something happens without it in place?
I think you need to check the wiring very carefully. And check for shorts
or leakage to ground.

Tony's suggestion is the best at this point - look for issues with the
motor start and/or run caps. A shorted (or open..) cap can certainly
