What is it?
Found this in an old tube caddy. It is a Perma-Power CRT adaptor of some sort. 10BP4 era. No readable part #. A short adaptor at the tube about 1" long and all wired pin to pin. Inside are a resistor, neon bulb and a brown thing. They are wired across pins 2,10, and 11 (G/K) but not the filaments. ???
