Zenith Model 288 Tombstone Radio (1934)
This large art-deco model 288 tombstone was one of Zenith's first
all-wave receivers. It was introduced late in 1933, ready for the 1934
season, at a sales price of $69.95. The model shown here features
the 8-tube 2056 chassis, having 5 frequency bands, a three-gang
tuning condenser, an RF stage, 2 IF stages, phono input and a total
of 6 control knobs! (See Riders Zenith page 4.15 for the schematic; the 6-
knob type 2056 chassis is not shown under Zenith model 288 @ NostalgiaAir).
The radio is sometimes referred to as the model 288 Challenger
Tombstone, presumably because in 1933 Zenith had issued the
following challenge to both the radio buying public and to their
Cones and Bryant, in their book "Zenith Radio - The Early Years
1919 - 1935" state that the styling of this and similar contemporary
cabinets by Zenith marked "the first incursion of modern industrial
design into the Zenith line".
The tube line-up is 58 (RF amp), 58 (mixer), 56 (LO), 58 (1st IF), 58
(2nd IF), 2A6 (detector/AVC/1st AF), 59 (power amp) and 80
rectifier. Frequency coverage is in 5 bands from 540-1560kc, 1.45
-3.4mc, 3.2-6.9mc, 6-12.6mc and 11.5-25mc. The 6 knobs perform
the functions of, from left to right, tone control, volume/on/off, tuning
(upper center), sensitivity/phono-jack-switch (lower center), band
switch and short wave antenna trimmer.
This radio also allegedly came with a 2051 chassis that had 8 tubes
but 5 knobs instead of 6. Although I have never seen a photo of this
variant, I did come across an illustration of a 5 knob set in an early
advertisement - it had no lower-center knob.
