Start motor fails to engage

[davida@humnet.ucla.edu (David Anderson)]

Hi all,

I'm trying to help a little old lady get her M-3 working again.  It's fine
except that the start motor fails to engage the tone generator gear.  It
turns and moves toward the gear, but just barely fails to engage.  If I
push it into the gear, it starts the organ just fine.

My question: can the present motor be fixed, or is a new one required?
I've never encountered this problem before.

Also, she persuaded me to cart away what I discovered to be a Hammond Type
F power amp with full tube complement of 2A3s and 56s.  I checked it out
and powered it up with the rectfier out (I don't trust high voltage caps
quite that old, and I have no speaker coil load for it).  I measured 520VAC
across one half of the power transformer, but only 340VAC across the other
side.  (I can't measure the rated 1050VAC with my digital meter).  I
suppose this means that the power transformer's high voltage winding is
screwed up somehow.  The filament supplies were fine.

The 2A3s measured around 78%, while the 56s and 5Z3 rectifier measured like new.

Any ideas on what to do with this thing other than make it into a piece of
living room art?

Regards,
David Anderson
