What is this part in old radio?

[johnr66]

I have an old tube AM/FM table radio (circa 1960). There is one component that has several pins in-line, like a SIP IC, it is dipped in the tan colored coating like ceramic caps. What is this part? Thanks

Probably a Milti-capacitor.

I have several old tube radios dating from the early 40's a a few of them have them.

Has several cap's in same body. Usually all same value.

Pictures would help a bunch

It's probably a PEC, often found in the tone control circuit.

It is a hybrid module. There were common in many old radios, and some stereo equipment (like Fisher receivers). It is a sub circuit built on a small PC board or ceramic substrate. The early ones used small discrete components. Later the resistors were printed directly directly on the substrate using resistive ink. During the 1960's surface mount components and semiconductor devices were added. Modules like these were still common in high tech devices (we used them in pagers and two way radios) until cost factors caused them to fade from use in the 90's. They are still found where cost is not the major issue, and protection from reverse engineering is important.

Unfortunately it is rather hard to find out what is inside the module if it is defective (not uncommon). I have taken them apart but had very limited success at reverse engineering.
