Radios



This above Admiral radio was in my grandmother's kitchen.

My brother and I had an Admiral B&W TV set just like this one (model 24R12) back in the '60's when we were kids. Diagram

Airline 83BR-502. No logo anywhere on this radio. Superheterodyne without an IF stage, 300ma heater string with ballast.




This Airline 62-508 radio is a superhetrodyne with 150ma heater string tubes.


DeWald model A500

Emerson





This Emerson 708 B was my Grandma's:
It also came in ivory, blue, green, and red.

A Hallicrafters that is not a boatanchor:

TRF set: 12BA6 RF, 12AT6 triode detector, 50B5 audio output, 35W4 rectifier.


A Canadian radio: It's ready for the extended AM band

Olympic LP163, 6-501

LP213, 6-604


This radio was made in mainland China. Its shortwave bands were disabled by someone who shorted the respective local oscillator coils to ground. I usually recap all my radios, but I kept this one original (still, it does work).
A Philco radio from New Zealand:
Like Australian radios, this one has radio station callsigns on the dial (#xx format). Runs on 240VAC, has a power transformer, uses 4 tubes: ECH42, EAF42, EL41 and EZ40.
A Philco Tropic radio from Lima Peru:

This above right Philco looks a little like Robby the robot.




More than just a defense contractor

RCA tube radios

My first bakelite set, the RCA 8X541,
acquired in 1970 at a church fair

Zenith tube AM/FM


An earlier version (right) of the above set had the old 45MHz FM band included.
In 1945 the FCC decided that FM would have to move from the established 42 - 49 megacycle pre-war band to a new band at 88 - 108 megacycles, to make way for television. Both in frequency spectra and consumer dollars. RCA's David Sarnoff in particular wanted FM to "go away" so the public wouldn't be distracted from buying his latest up and comming product: televisions. More than half a million FM receivers and some 50 transmitting stations would be rendered obsolete.
Model 7H820H, also has 45MHz FM

Zenith 45MHz FM radio model 8H023 (with 100MHz FM, and AM)
