In earlier sets like this one, same as in larger radios with more serious acoustics Philco did not use the field coil as the main filter choke (that also would require hum-bucking wire) but did use separate large chokes (also in 20, 70, 90, 16, 116 and its permutations, and all those early consoles whose chassis look similar to yours) that look like a mid-size transformer.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

I doubt it would introduce any noise. We use similar lamps for the panel indication, 12V AC lamps: they are LEDs...morzh — 02:15 PM |
