GE C435A (blame this radio for getting
me into electronics
and electrical
engineering!). Acquired in 1970.
I always knew GE was a Mickey Mouse operation! Model C2418A
This GE 422 radio is not "rare", it is "well done" :-).
A leading consumer journal rated the GE 422 as "very good" back in 1953.
It has an RF amp stage, three gang tuning capacitor,
and good audio. It is a
very good radio, nice DX machine, especially with a 12SG7
tube in place of the 12SK7 in the RF stage and
a 19HR6 in place of the 12BA6 in the IF stage. Below is an advertisement
about this radio:
This FM tuner uses octal tubes! Model XFM-1
Combination digital clock and digitally tuned radio receiver. Keyboard
gets dirty quickly, making keys inoperative. Long term fix: disassemble
keypad, clean contacts, then place a plastic sheet (cut from a zip-lock bag)
between the metal keytops and the black foam holding the plastic keytops in place.
Did this 4 years ago, keyboard still works fine.
The GE model 1284A set above needed its
high voltage audio output transistor replaced. Used an NPN bipolar transistor
from the switching power supply of a junked monochrome monitor to
replace it, worked fine. If you have a GE radio like this one
that is dead, check the output transistor. I've had several with bad output transistors.
This GE C1580Z is the 1284A
with clock.
The homebrew set on the right uses GE circuit boards
almost identical to those in the GE T1290A set above
and the GE T2240H set below.
Note the unusual calibration of the AM dial of the homebrew set.
A different cabinet for the GE-T1290 
A similar set labeled "Musaphonic" 
< GE model T2240H . 
My brother had a Grundig set very similar if not the same as this one,
but he needed room so he sold it to a radio collector.
A garage sale find for $5.00 and after a switch cleaning and recap
works fine. AM/FM table set with 3 tubes. Hot chassis, don't let the power
transformer fool you, it's just
for the heaters.
