General Electric (G-E) Model K-62 Console Radio (1931)
G-E K-62 - The Popular Console
The G-E Popular Console.
The General Electric model K-62, introduced in the fall of 1931, was
referred to by G-E as their "Full-Range Popular Console". The
purchase price was $124.75, complete with tubes.

It was claimed that this was one of the G-E models to have participated
in a series of blind
tone tests, attended by prominent musicians of the
day. Full-sized console radios from four well-known manufacturers were
hidden behind screens and voted on for their tonal excellence. When
the votes were counted, the G-E model was claimed, in test after test,
to be the winner.

"Believe your own ears! Hear the General Electric before you spend a penny for
radio. In the first minute you listen, you will understand why this great G-E
instrument won every tone test, why it is the one radio for you. Here is glorious
tone reality. It is like looking at a vivid autumn landscape, after viewing it in a
black and white photograph!"

The K-62 offered the following list of features, extracted from G-E
advertising,

  • A 9-tube deluxe screen-grid superheterodyne
  • new,  exclusive G-E tone equalizer. counteracts effects of cabinet     
    resonance, preserving tone fidelity of dynamic speaker
  • Two pentode output tubes.
  • Automatic Volume Control.
  • special phonograph terminals
  • chassis cushioned in rubber
  • Superb brown walnut cabinet with rich-grained butt-walnut overlays
...the choice of leading musical artists & symphony orchestras.
The K-62 is a 9-tube superheterodyne with coverage of the standard broadcast band. The tube line-up is 235 (RF amp), 224
(1st-detector), 227 (LO), 235 (IF), 227 (AVC), 227 (2nd detector), 247*2 (push-pull output) and 80 (rectifier). The schematic is the
same as for the
RCA model R-11.

The radio includes a tone control circuit, comprised of a series connected capacitor and variable resistor, wired between the control
grids of the type 247 output tubes. This mostly acts as a high-frequency cut. However, at the lowest resistance setting the capacitor
and secondary of the AF driver transformer creates a resonant circuit, providing a degree of bass boost.
