[Boatanchors] HT-37 transformer questioni

[Glen Zook]

According to the HT-32 manual ("plain" HT-32) the part
number for the power transformer is 052-400477.

According to the HT-32A, HT-32B, and HT-37 manuals the
part number is 052-400673.  Therefore, those 3
transmitters all use the same power transformer. 
However, the "plain" HT-32 does use a different
transformer.  But, the specifications for all of them
should be the same.

Just in case you have not already considered it, I
would definitely replace the tube rectifiers with
solid-state.  I do not usually recommend doing this
except in certain circumstances.  The power
transformer in the HT-37 and HT-32 series is running
at the "ragged edge" and removing the filament load
for the rectifiers really does help with longetivity
of the power transformer.

The Heath DX-35 and DX-40 are also examples of the
overloaded power transformer and replacing the tube
rectifier with solid-state also helps with those
transmitters as well.

Is the power transformer in both the HT-37 and HT-32
the same, that is, with the same physical dimensions?
 
I just received a power transformer supposedly from a
HT-37 and this transformer is smaller than the one
that was in my HT-32A.
