Help with a Admiral Portable TV ,1950's

[DavGoodlin]

Transformer-less TV sets have a few more precautions than the 1940's radios did.
A polarized plug (and interlock) was usually found on a 1950's TV, but not a plastic-case radio of the same vintage. Many of these radios have the metal knob-shafts insulated from the chassis via a capacitor and no other exposed metal parts.

No fuse or breaker will clear at the 30 milliamps that it takes to electrocute.

Ground fault circuit interrupter GFCI receptacles are always a good idea for any work bench and are code requirement for basements, garages, outdoors, kitchens, bathrooms and within 6 feet of a sink. The cost is about $12 and can save your life.

I use a neon tester to verify if the shorter slot of a receptacle is connected to hot/line side/black wire and the wider slot is neutral/white (the same as ground).
