1952 Newcomb RC-12

[Hi-Fi-Mogul]

Another of the many Hi-Fi gals almost completed.

This is an uncommonly found 1952 Newcomb RC-12 with a
V-M 950 record changer.

Power transformer model using 6X4, 6V6, and 6SQ7 tubes.
The 6SQ7 triode is the only section of that tube used.
AC line fuse.

Speaker: 6 x 9 inches.

The cabinet covering needed gluing down in some
spots.

To treat the flea-bites, I tried a little Howards Restor-a-Finish
mahogany on the bottom to test the results.
It looked good after curing a few days outside, so I went
over the entire cabinet, and it is much better in appearance.

Outside of the e-lytic filter caps, there was only one
bumble-bee 0.047 mF installed across the cabinet On/Off switch.
Other caps are ceramic.

The V-M 950 changer dates from Sept 8, 1952.
Per Gary at V-M, it has the earlier RMA stamp code vs. the later
V-M factory code.

After cleaning/lubing the motor, I used a square O-ring replacing the
old rubber on the idler wheel.
For the 33.3 rpm speed turret, I used a cut-down rubber
grommet to replace the old rubber.

6X4, 6SQ7 tubes had production dates of 1952.
The 6V6 was from 1954.
The 6SQ7 had a bad diode section, and I
thought it best to find a tube with all sections good.

Did an audio bench test today, and the amp is quiet,
and the changer is almost there.

I need to tweak the record support arm, as
it is not dropping easily, though its been
cleaned and lubed.
And the AC cord needs a new plug.

When it's all back in the cabinet, this is one
heavy player, but a nice one.

Nice job, Mr. Mogul, I really like the way Newcomb did their in cabinet schematic. Very easy to read and lots of information there. How does it sound?

Bill,
I used another 6 x 9 speaker for the bench test,
but it was not in an enclosure.
The output though, was nice and clear, no hum.
Vol & Tone controls work well.

After I get the changer 100%, I'll see how the
Newcomb speaker sounds.

Do you have the EIA code off the Newcomb speaker? I have a Newcomb player that needs help. Parts aren't easy to find, at least the ones I need. Nice job, Mr. Mogul. You find the good stuff.....
