I've never heard/read a single thing about 1930's battery radios. The
ones I know about were all from the 1920's. They take the 201 and 301
tubes. Most were made to take 6.5 volts for the filaments as car battery
rechargabe wets of the time were all 6.5. Here is the interesting thing.
Those tubes dont need that much juice. The rigs bump it down from 6.5.
There were some 201 and 301 tube radios that have direct voltage to the
tubes. If you hook up 6.5 volts to the filaments, kiss the tubes goodbye.


01A/201/301/etc. used 5V filaments. Many radios using these tubes ran
6.5/6.6V auto batteries and had an adjustment to allow for voltage to the
filaments to be varied so that as the battery ran down, you could turn the
voltage back up a bit, thereby getting longer use out of a charge of the
battery.

I was mistaken about those tubes, then... I thought the 01A filaments took
less then 5 volts.

Battery radios were made clear into the 1950s or so for use on farms
where there was no commercial AC power. Also there were portable tube
radios that ran on batteries.

I had a Zenith SW that used and ate batteries at a phenomenal rate. Made
in 1952. Had nice audio, but if you played it loud, you sure didn't play
it very long. Batteries cost a lot of money too, and were pretty hard to
find.

Take a Windmill or Water Wheel plus
an old Car/Truck 6 VDC Generator and
Regulator and a 6 Volt Battery.

Lot of 'far out' rural and country places
still had old 12 Volt Lights for use for a
few hours at night.
