From its serial number it looks like this radio was
the 480th unit off of the assembly line. It was a relatively expensive
radio in its day when you consider that you could buy a new
car for a little over $500. In 1933 this radio sold for $92.50 in US
dollars according to Morgan McMahon's book "A Flick of
the Switch". With inflation that would be $1,861.26 usd
today or $2,481.68 in Canadian dollars. When you
consider that the average wage in 1933 was about $1600 per
year the average family could not afford this luxury radio.
The circuit is shown at the right. The
power transformer is also capable of operation at 240 volts
for export. The radio is an 8-tube superheterodyne with push-pull Class B
audio output. Unusual for the day the radio has two stages
of tuned Radio Frequency amplification in its front end.
This coupled with its internal antenna, makes the radio
quite sensitive and unlike most radios manufactured in the
early thirties it easily picks up stations without the need
for an external antenna.
This radio uses 2.5 volt vacuum tubes
and is solidly constructed. It was one of the most
challenging restorations that I've taken on. Most
parts are buried under the complex bandswitch and RF coil
assembly or are mounted on terminal boards. This complete
RF assembly must be removed in order to gain access to the
components that are buried underneath. Checkout the
