Inside a Nike Hercules Guidance Circuit Board
Here we have a Circuit Board, number 9158790, Electronic Switch. This technology is late 1950’s so you have a double-sided circuit board with traces on both the top and bottom. A smattering of resistors, capacitors, relays and mini-transformers. On each side are 2 miniature vacuum tubes with wires soldered on to the bottom pins . The 4 tubes are encased in a metal tube shield and have a heat sink that is fixed on to the circuit board. There is number on every tube T3 361 N I have not been able to cross-reference that number with a Western Electric Tube. The closest thing I can find is a Western Electric 361A listed as a pentode type.
