Allen Brtadley pilot light question

Does the unit still work? I know some definitely had a TINY transformer in the back of the fixture, and the windings must have been made with insanely fine wire. So, I'd check to make sure the unit isn't actually defective.

I can't imagine they used any serious electronics in 1966 for this purpose. (Or, is 1966 the bulb number? But, I can't find one of those.) Is there any possibility this unit has the wrong lamp in it? If it was for a neon lamp, it would have a series resistor, and would appear open circuit with the neon bulb in place.

Oops. It was a GE 1866 bulb.

Lights up just fine, so the circuit still seems to work.

Not very bright, but incandescent with a strong green filter is not very efficient.

They seem to have two kinds of transformers for this. One is exactly what you'd expect: two 120 V gozintas, two 6.3 V comesoutas - 800T-N326.

The other kind has *three* 120 V gozintas and two comesoutas, and either has a relay (800T-N296) or some diodes (800T-N920N) inside. This seems to have something to do with providing a "lamp test" input that's independent of the "regular" input.

If you have the three-gozinta kind, you have to pick the right two gozintas for the ohmmeter. I think.
