1930's Style Regenerative Shortwave Receiver

This one is a two-tube battery type using 1N5 and 1A5
tubes. Three plug-in coils are provided to allow shortwave
coverage from approximately 3.5 MHz to 15.3 MHz. Tuning is
accomplished with a nice 1920s vintage E-Z Toon dial with a mechanical
veneer and an approximate tuning chart is included.
The wooden cabinet is stained and finished with hand-rubbed
lacquer. There is a compartment underneath for storing batteries,
log sheets or headphones. The rear cover is removable
for convenience.
The radio operates from batteries. 1.5 volts is required for the
tube filaments and 90 volts for the plate voltage. Ten typical
9-volt alkaline transistor
batteries will provide up to 140 hours of use and one C-battery will
give about 70 hours of use.
It operates with 2000-ohm high impedance type headphones and external
connections for antenna and ground. It easily receives
stations from all over the world with good volume with the thrill of
operating a set in the style of radio's early days.
