Rotor/motor for late sixty's RCA Vinctor record player

by bobafett » Sat May 09, 2015 3:29 am

Hello all, I need to find a replacement rotor + bearings or a whole new motor for my late sixty's RCA Victor record player. It's a vht 89 wk.

If you have any info that I could use, I would really appreciate it.
Thanks.

To anyone who has a "vintage" phonograph:
Those blurry photos above are mute testimony as to what happens to those small induction phono motors over time - IF THEY'RE NOT LUBRICATED.
If you have one, and even if it "runs fine" to you, have it serviced if you value it.
The years of neglect aren't pretty on these things, or your wallet.
A typical induction motor of this sort is likely to set you back as much as $100 these days - simply because they're scarce.
You wouldn't drive a car for 50 years without having it lubed and checked, would you?
The Internet is a marvelous thing, however it's not a good substitute for actually being there.

I have been able to save many motors of this type, by chucking the armature into my drill, polishing the bearing surface with crocus cloth. Then I clean the bearings, with a "safety solvent", and re-oil it with 20wt ND oil. Ron Rich

Thanks, and sorry about the poor quality of the pictures. Do you know where I could actually purchase one though? That is really what I need.
Thanks.

Yeah Ron, but look at the pics - that motor is HISTORY!
Worn-down and scored shaft due to decades of running "dry"
And no,... ND20 oil on those changer motors is not acceptable - only lightweight "Zoom" oil.
Because that 20Wt will cause a slow-down of speed, noticable on records.
I know this for a fact.

I appreciate your advice. What I really need though, is where to find one. I can't oil it until I have one.
Thanks.

Finding a replacement motor is a job, surely.
But that's part of the problem with these "Studiomatic" changers.
The mechanisms also need a complete overhaul, including a teardown of various assembles, proper removal of old lubricants, and re-lubing.
Until that is done, reliable operation and performance will not happen.

Trust me, I've done enough of these to know.
