[Hallicrafters] HT-32 to HT-37

I personally believe that there is entirely too much being made over the 
HT-32/HT-37 transformer.

I've got an original HT-32A.  I also had an HT-37 that I ran from 1980 
through about 1986 or '87 when it went to a High School.

The only real issue are the filter caps.  Replace the old ones with new 
ones.

I've been running this HT-32 for 12 years.  Original transformer, 
original 5R4GY rectifier.

Works just fine.   Yes, my line voltage runs between 125 to 127 VAC.

Transformer and rectifier are happy.  It most likely IS running at or 
above saturation.

This is no different than my BC-610 and T-213 that are being run at this 
same line voltage.

Both were designed for 110VAC.

Neither has had ANY problems with the 125 to 127VAC source.
