Hello,


You can use any turntable motor from any of the 1100 mechanisms from
the
1963 Model L through to the 1976 R-80 and the1200 mechanisms from
1976/77 R-80S through to 1979 R-83.


If you get stuck I could supply a good used one, but I am in the UK.

Thanks Alan, that's good information to know. *I did manage to get one
at jukeboxparts.com. *Paid $75 for it. *Seemed like a fair price to
me. *Just hope it fixes my problem. *The speed is slightly slow and
has a slight wow. *I opened it up and two of the coils had hot spots
where the varnish was burned off and a few of the wires shorted
together. *I replaced the idler wheel and it made no difference even
though it had some nicks in it. *Do you think I am on the right track?


Hi,


Have you replaced the idler wheel with a new one or just a used one?
You need to check out that motor with regards to wear on the top and
bottom bearing, remove any old caked on oil and re oil, if the shaft is
worn on the bottom or top then the motor is no good but by the sound of
it with shorted windings it is not at its best.
If you were in Europe then there is a speed spring fitted to the motor
shaft to alter it from your 60hz to our 50hz (these wear and need
replacing).


The way we test for problems with speed is to put a record in play and
hold the edge of the record, the turntable under the record should keep
turning strongly, if it does not it is usually the idler wheel and
linkage that is the problem.


Have you changed the three motor grommets? (part number 200-11501)

Hi Alan,
I'm getting the new motor tomorrow so I still have the mechanism
apart. * I'll try your suggestions after I get the new motor in. *I
sure hope the motor change takes care of it. *The idler wheel was a
used one so now I'm a little worried about that. *I got it from this
jukebox parts place so I wouldn't think they would send me a worn one
but who knows. *Holding the record to see if it still turns sounds
like a good test. *I'll report back after I get the motor in.
Regards,

Hi Alan,
Got the new motor, installed it and the speed and wow problem is
solved. Whew, I was a little worried. I have another problem now
that I actually had before I changed motors. The sound has what I
would call a consistent low frequency sputter that is there only when
the needle is on a record. It is dead quiet with the tone arm lifted.
It is not really loud but noticeable when you listen for it. I'm
thinking it is turntable noise coming through the cartridge or there
is something wrong with the needle or cartridge with the way it is
tracking. I have a new needle coming so will try that first. Any
thoughts.
Thanks,
Bob
Hi Bob,

Have you changed those motor rubber mounts? This could be the problem, also you said there was some dings in the idler wheel this could also be the issue. How long have you had the styli in the cartridge? also have you looked at the stylus when it is on the record is it being forced onto record. this could be there is an issue with the styli or the tone arm settings.

Regards
Alan
