found this radio in a Maryland antique store in the 1990s. I
found an 120Vac outlet in the store and plugged it in for a test. We
could hear sound but with a loud hum. I figured all it needed was
a new power supply filter capacitor and took it home for a cost of
$25.85. Although not a bargain, I was very happy that it was an RCA Victor brand, a very
historic name in the radio industry.
I kept the original paper price tag and taped it to the bottom.
I got the radio home I unscrewed the back and the chassis and slid the
metal base out of the case. I also found the schematic online and
installed a modern electrolytic capacitor into the chassis in parallel
with the old one. Although not period correct, the mod is hidden
and should not detract much from the vintage electronics. This
repair fixed the loud hum.

radio is shown above. The left knob is the power/volume control,
the middle is the tuner mechanism and the right toggle switch for tone
control (treble cut or normal). The radio is available in various
cases per the manual, and I presume the same chassis (or variant) would
be used making this the common aspect for this line of radios.
Available cases were Walnut (this one), Blonde Wood, Mahogany,
Brown Plastic and Ivory Plastic.

an AM radio, the sound loudness and quality is highly affected by the
signal strength and the orientation of the antenna loop to the radio
tower. You will be able to hear clicks and pops from nearby
electrical appliances turning on and off, and thunder storms will sound
like crashes. Incidentally, I thought of building a lightning
detector some years ago by using a small AM transistor radio set to an
unused channel. The loudness of the crash sounds would tell you
how close or intense the lightning is.
Label on the bottom of the radio is in real good shape. Surprisingly,
the radio will also work on 120Vdc.
