Majestic (Grigsby-Grunow) 608 "Mayfair" Table Radio (1933)
Copyright TubeRadioLand.com
Grigsby-Grunow's Majestic model 608,
nicknamed the Mayfair, was announced in
the December 1933 issue of Radio Retail-
ing (see below), making it one of the very
last in the Company's line of Smart set
radios, released just prior to their bank-
ruptcy. Ironically, it appears to have been
an upgrade (with new chassis & updated
cab) to the model 411, which was arg-
uably the first in the line introduced back
in April of 1933 (see thumbnail below).
The similarity between models 411 and
608 raises the possibility that industrial
design for the 608 was the work of Milton
Rosenow and Albert Jenks of printers and
engravers Rosenow Co. of Chicago. Their
design patent for the model 411 can be
viewed here. Milton Rosenow was the
head of the company until his untimely
death in Nov of 1937, following an auto-
mobile accident while returning from a
Fairbanks-Morse refrigerator convention.
The 608's tube line-up is 6A7S (mixer/LO),
6E7 (1st IF), 6E7 (2nd IF), 6C7 (2nd det-
ector/AGC/1st AF), 43 (AF power) & 25Z5
(rectifier). Its type 600 chassis uses a res-
istive line-cord. Tuning range is from 540
to 1730 kcs standard broadcast. The
schematic may be found here, courtesy of
NostalgiaAir.
