I have a Philco 42-1010 which I have restored the cabinet and radio but the phonograph is in terrible condition. The phonograph has a very unusual Light Reproducer circuit that uses a mirror on top of the needle, a light source focused with a lens and a photo diode sensor to sense the osillation of the vibrating needle/mirror. Does anyone know anything about this type of phonograph and is it possible to restore??
I would like very much to try as it is very unique.

Hi Brian, I've emailed the service information for your Philco_1010, I hope it covers the information that you need. I suggest that you also check out Chuck Schwark's web site at http://members.aol.com/caschwark and if neccesary email him with your query. he specialises in Philcos and should be able to answer any of your questions. good luck, Don Black.

The light power source is the local oscillator in the set.

It's always a power amplifier, such as possibly a 7C5

in this set(I have one at home, but can't look now).

It operates at about 1800 Kc, as I recall, much as the

exciter light in a movie projector. In the phono position,

the oscillator becomes the exciter oscillator. Per Philco,

the bulb is a special 4 Volt gas-filled bulb. You can

use a type 55 dash light bulb, if yours is burned out.

The photo cell is a selenium cell,which generates a signal

with light on it. On these Philcos, the light is aimed

with the screw on the base of the pickup head, to be half

on and half off the cell. Selenium cells are relatively

slow in rsponding, thus the lousy frequency respnse of

this pickup. They had lots of boomy bass, and people

loved it. I tried unsuccessfully once to gin up a silicon

solar cell to replace the dead selenium cell in the

pickup. I understand that it is done, and I have heard one

that was rebuilt that way. It sounded much better than

the original selenium cell. I'll have two of these beasts

to make work: a 42-1003 and a 42-1010. I'll get to it

some day. Once the pickup is working, then get the

changer turntable drive working. If you're successful,

you will have done the (Near)impossible. Philco sold

conversion kits for the turntable drive during the

war.

:Mid Atlantic Radio Club had an excelent article
:on rebuilding these Beam-o-Light reproducers.
:It was about a year ago,and back issue is probably
:available(RADIO AGE). If you need more,let us know.
:Keep your knobs polished and your tubes warm!

I have a philco 42-1010 turn table in my garage....I think but I don't know much about it. It might be in better shape than yours or not...I uncovered it in a basement. Let me know what to look for and I might be able to help out
