Long time no post. I've just retired and now have a few free weeks before starting my next career, so I went through my basement cleaning and pulled out this purchase. It is a Majorette Stereophonic model 500, with a VM changer.

Ok, first, I assume I clean the motor and shifting mechanism, and lube, just like an RCA. It is part of the 1200 series, but I don't know which, is a guide available to help dissasemble (I have a djvu file for the RP 205 which comes in handy)?

Lastly, it is a 3 tube amp (Two 50c5 and a 12ax7) which from what I see shouldn't be too hard to recap, but... I can find no listings for this brand or model in the schematic for purchase libraries. Any suggestions on where I might find one? I'd feel more confidant if I had an idea how this stereo amp is set up.

Hello Mitch,
I believe I found the chassis schematic for your Majorette.

Could you supply some component information ?
1. Electrolytic caps' values on the can
2. Sharp photo of the inside of the chassis
3. What the resistor value is immediately prior to solid state
rectifier (neg side of rectifier).

Send me a PM with email address, and
I will send you VM diagram and schematic.
You can compare with chassis components.

Here's a great photo restoration thread for the
V-M 1200 series changer :

Also, the V-M appears to have a crystal phono cartridge, which
may have already degraded from age.
Will probably need replacement.

Thanks,

I'll try and disassemble it again tomorrow. Is the best bet to order a new Idler regardless?

Mitch

You can remove and clean the idler and inside
rim of the platter with alcohol.
Then, if the idler grips well through cycle, it's good.

If not, order one from the Voice of Music.com
Exchange of old idler is required.
