Majestic (Grigsby-Grunow) 55 'Duette' Mantel Radio (1933)
...as different from ordinary radios as sunshine is from rain.
Grigsby-Grunow's model 55, known as
the Duette, was one of their series of
"smart set" models for 1934. It was int-
roduced during the summer of 1933 and
initially listed for $35.50. On the whole,
the 1934 line represented a novel direc-
tion for Grigsby-Grunow in that the mod-
els were smaller and less expensive than
their previous fare.
The 5-tube model 55 has tube line-up:
6A7S (mixer/LO), 6F7S (IF amp pent-
ode/1st-AF triode), 6B7S (2nd IF amp
pentode/AVC/2nd detector), 42 (AF
output) & 80 (rectifier). Through their
use of three spray-shielded "duo" type
tubes, Grigsby-Grunow claimed 8-tube
performance for this model. The schem-
atic for the type 500 chassis used may
