Antique Turntables

I recently purchased an antique Stereo Cabinet/System. It is branded Stromberg Carlson, but was built my General Dynamics. The Cabinet and components are visually flawless and look as if it was built yesterday. Since the unit is at another location being repaired I don’t have any more access to more details of my unit. I believe it was built in the late 50’s possible into the 60’s. I have all of the original documentation with the unit at the repair facility, several miles from my home. The only information I can provide at the moment is below.

It is a Tube amp with a Preamp as well as a Turntable. I knew it needed work, so it is being repaired as there was a nasty hum and the turntable would not work. It is now several weeks later and the Amplifier has been repaired by replacing a badly leaking Cap, so the hum is gone as well as the crackle from all the dust cleaned out from the inside of the Pots for Volume, Bass, Treble and balance.

The turntable is receiving power but the mechanisms in the turntable changer that engage with the motor are just frozen. So the only way to return the Turntable to functional condition is a donor table to replace the frozen parts or an outright replacement. I would like to keep the unit original.

The model number of the Turntable is a Stromberg Carlson PR520 or lower end PR510, apparently the Turntable was also sold under several other brands as well. One of the other brands model # is Glaser-Steers GS-400.
I would appreciate any input into locating a suitable Turntable replacement or Donor Turntable.

Nice find, tardisjohn ...

I don't have any info for you, but I'm curious as to what brand the electronics are. There were some pretty nice Scott electronics put into some of the consoles in their day.

I love the old stuff that we had as kids.

I once saw a Fisher console with a Sony reel to reel, a Dual 1229, and 12 inch 4-way speakers on each end, with a loaded receiver to power it.
The whole set cost under $2K (a whole lot of money in 1967 or so).
The furniture was extremely solid and nicely finished. I almost died on the spot when I heard it, but we were in the market for a Fisher stereo compact- a  turntable set into a hollow space on top of a receiver with
separate speakers. But even that wasn't all that bad (although I hated the turntable). Things were coming along though- the equipment becoming available dropped the TV tube in exchange for separates.
The TV consoles were useless- a good thing. None of them sounded even OK. 

No matter how frozen, any mechanical system can be revived.The real problem is the lack of ability to understand the complex gizmos in many changers. If Rube Goldberg had nightmares, they are probably about record changers.Worst is where missing springs cause all sorts of failures of parts to cooperate...
