Those old radios were not grounded.Be careful, don't let that old radio
electrocute you.

There is a newsgroup where some people work on and restore old radios.It
isn't alt.binaries.pictures.radio newsgroup, but ask those folks in
there.

I'm sure a battery operated radio will eletrocute someone. Why don't you
educate youeself before opening your mouth?

You're thinking that a battery operated radio is a transistor radio. Vaccum
tubes generally use higher voltages. If you had read the original post,
you would have seen that one of the batteries was 90 volts. That's enough
to kill you if you are not careful.

Ironicaly, at about the time the transistor was invented, low voltage,
cold cathode (no heater) miniture tubes were developed. but that was 20-30
years AFTER this one was made.


That's also where the battery terms, a,b,c etc came from. An A battery
was a cathode (heater battery), a B battery was the high voltage
and a C battery was a "bias" voltage.

A batteries were generaly 1.5 volts (single carbon/zinc cells), but B
batteries ranged from 45 to 90 volts. There was a special 512v battery
used for electronic flashes in the 1950's, but I don't know if it
was called a B battery or not, I've always heard of it referred to
as a 512 volt photo battery.

It would have made a nice B battery for a small radio transmitter.

A 90 VDC battery can delivery a lethal shock.
