Philco Model 37-600 Table Radio (1937)
This is an entry level though stylish radio that covers standard broadcast from 530-1800kc. It
features an ac-powered 4-tube super-heterodyne circuit having tube complement:- 6A8G
(LO/mixer), 6J7G (2nd-detector/1st af), 6K6G (AF output), 5Y4G (rectifier). In common with
many of the 4-tube Philcos of the era, regeneration is applied around the 2nd detector tube in
order to boost gain and compensate to some extent for the absence of a dedicated stage of
IF amplification.
I have fully re-capped this radio and replaced a number of resistors that had drifted high in
value. This is not a hot performer, even with the regeneration control (accessed from below)
peaked up. It also suffers from "blasting" unless one is mindful to turn down the volume
control when tuning from weak to strong stations. The sister model 37-602, which looks very
similar, features an additional tube, providing IF amplification.
The cabinet has FAUX wood grain on both the front and back faces and the chassis is loaded
from the bottom. It is often referred to as a double-sided radio for obvious reasons. The
model photographed has a reproduction dial from Rock-Sea Enterprises and the lower knob
(volume/on/off) may not be original.
