A Canadian radio: It's ready for the extended AM band
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
the Tasma "baby" model 1001:
The little map of Australia on the dial is a nice touch. It uses a 6A8 converter, an EBF2GT IF amp and detector,
an EL33 audio power output, and a 5Y3 rectifier.
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
Model 7H820H, also has 45MHz FM
Zenith 45MHz FM radio model 8H023 (with 100MHz FM, and AM)
