The J-100 was General Electric's top of the line table model
radio for 1933. This radio was actually manufactured by RCA-Victor
which manufactured it's own version as the R-74. The construction
of the chassis is much like that of how Majestic (Grisby-Grunow) built
their radio chassis, like a tank, using thick gauge steel and heavy duty
electronic components. The J-100 was essentially a 10 tube
console radio chassis housed in an elaborate cathedral cabinet and the
whole set weighed in at a hefty 44 pounds. An unusual feature
about this radio is that the volume control works through, and is part
of, the AVC circuit as compared to most radios with AVC where the volume
control functions separately from that of the AVC circuit.
I purchased this set, in May of 2000, at the IHRS Spring
swap meet which was held in Indianapolis, Indiana. Electronic
restoration was difficult because of the extreme crampness of the
chassis and the way components were mounted, overlapping each other,
inside of the chassis.
