Philco 37-610B Tombstone (early version, June 1936)
This is the early version of Philco's 37-610B Baby Grand
tombstone radio for the 1937 model year. It was introduced
in June of 1936 with a retail price of $42.50. The later style
can be seen  

These entry-level Baby Grands made extensive use of FAUX
grain on their fascias. Faux grain is essentially a printed patt-
ern used to replicate the appearance of the genuine exotic
veneers found on some of the more expensive sets of the
day. The idea was valiant in its conception but fell short in
practice, as the finish weathered the rigors of time poorly
and even when new, fooled practically nobody. Today, the
finish on many of these sets is badly deteriorated and poses
a challenge for restoration. Luckily, my set's finish is basically
good. It received only minor touch-up from its previous owner.

"This flat-top Baby Grand features authentic
reproductions of light golden-toned butt walnut,
gorgeous burl walnut, and straight grained American
Walnut. A striking contrast is afforded by the
dark-toned base moulding".

The 37-610B's Color Dial
The 37-610B is a 5-tube AC-powered superheterodyne
covering the three bands:- 530 - 1720kc (Standard Broad-
cast), 2300 - 7400kc (short-wave 1) and 7.35 - 22mc (short-
wave 2). The tube line-up is 6A8G (mixer/LO), 6K7G (IF),
6Q7G (2nd det/AVC/1st AF amp), 6F6G (AF output) & 5Y4G
(rectifier). The undistorted output power developed into the
loudspeaker is 3 Watts. The 37- 610B uses the code 121
chassis, whose schematic may be found
here, courtesy of

The code 121 chassis serves also for the
37-610J console
radio (photo at The 37-610T table set  
embodies the code 122 chassis, having the rectifier tube re-
located from the power transformer bell housing to the chas-
sis in order to accommodate the reduced internal height of
that set's bullet-shaped cabinet. Otherwise the code 121 and
122 chassis types are identical.
