Edison C4 Radio/Phonograph

[cdbpdx]

I brought home an Edison C4 that had been sitting in a barn for several years and didn't hold much hope that anything was functioning, but I found out at least the turntable still works just great! That is, it goes 'round and 'round just like you'd expect. It is also extremely quiet. The speed control works great, too. 78 rpm is dead center on the speed control dial.

You can watch the turntable spin on YouTube at: youtu.be/PXNufBPzgiA

Haven't tried the reproducer yet..Do I need a special needle/stylus for the reproducer?

Also, there appears to be 2 radio/amplifier chassis. The upper one seems to be all there, the lower one is missing a tube. All the tubes present match, all being Cunningham brand. I'm hoping that everything will work when I figure out what tube to install.

The cabinet is solid but the surface is not so wonderful. Needs lots of glue and surface restoration.

This is fun!  CDB

You need to get a wiring diagram (schematic) of this before you attempt any repair. Besides tubes that fail, there are other electronic parts that deteriorate with time and are possibly or probably bad inside the chassis of the electronics. Also the Magnetic pick-up will have hardened rubber holding the moving parts (the needle chuck), and would ruin a record if you tried to play it due to being stiff.This unit uses steel needles that are good for one record play each, and are held in place with a set-screw on the front of the pick-up.

The paper filter caps rated at 600 volts are trash, and, will immediatey cook the entire power supply. Also,those resistorsin power supply are always ope.
Most caps in these sets are in cans loaded with tar. The input transformrs, special to these sets, are often open.
All you can do is have them rewound. The cable wiring from the radio chassis to the power supply is often shorted.
If you actualy get it playing, fair warning. The pins from the tone arm pickup to the radio chassis hav 350 volts on them, and, will give you quite a jolt.
