zenith tuner module 175-5073-01 compatability

[zeno]

Only way to tell is look it up in the parts catologue. If
its physically the same it may work BUT your set uses
24V low B+ and the same year S-3 uses 12V. Other
difference is S-3 RAT tuners covered some CATV freqs.
If its one of the big dual tuners with 2 plugs on the side
resolder under the plugs & look for cold joints around the
shielding.
BTW drop a note to drh4683 he may have a parts catologue.
