The part that's missing is called a thermistor and is why it's dead. For testing just use a 5 watt or larger 15 ohm resistor.

Also anyone know what the black stuff is that peeling off the back of the CRT and making a mess everywhere? |

The black CRT coating is called "aquadag" It's conductive and grounded to form a capacitor thet filters the high voltage supply. You should recoat it once you've got the set working with something called "slip plate". https://www.slipplate.com/product/slip-plate-aerosol |

MG Chemical makes a similar product. It also come in a spray can.
Here is a version that you brush on. https://www.amazon.com/MG-Chemicals-..._&dpSrc=detail The aquadag falling off the CRTS of RCA sets of that era is common, I've got one or two sets with that problem. Thermistors frequently go bad. The fact that your's is unplugged might mean there is other problems. |
