[Hallicrafters] Need S-76 Main Tuning Dial

[Mike Everette]

As you may have discovered by now, the S-76 dials are
indeed white or off white translucent letters on a
black background.  The bandspread dial is either
calibrated for 80-40-20-10 meters, or 80-40-20-15-10
meters, depending upon the production run.  If the
main dial has an index dot for the 15 meter band, you
should have 15 meter calibration on the bandspread;
otherwise, not.  The 15-meter band was opened sometime
in the early 50s, I think.  The S-76 went on the
market in 1950 or 1951, before the band became
available.

I have no idea how to tell "early" or "late" runs from
the serial numbers.

Check www.antiquehamradio.com and you will probably
find what you need.  Be advised, you should try to get
a main and bandspread dial that "match" with respect
to 15 meters.

I have an S-76 and it's a fine receiver.  It is one of
the first generation of Hallicrafters
double-conversion receivers.  I have heard of, or seen
an ad for, the "SX-76" which is the same receiver as
the S-76; but since it used L/C filtering rather than
a crystal filter like previous "SX" receivers, the X
in the model number was dropped early in production. 
If someone has a radio actually marked "Model SX-76"
that would be a rare one for sure.

The S-76 morphed into the SX-96 by adding crystal
control in the second conversion oscillator, with
separate crystals for selectable upper and lower
sideband.  The SX-96 in turn morphed into the SX-100.
(And neither the SX-96 nor SX-100 etc. have a crystal
filter... guess Halligan figured that hams would think
an "S-" receiver was a cheapie... hmm.)

The SX-101, SX-111, SX-115, SX-117 and SX-122 all used
the same 1650 KHz/50 KHz IF scheme.  I think the SX-88
also used this design.  The SX-71 was double
conversion as well, but used a different first IF.
