Duane,

I hope you find a substitute because I have a HT-37 with both transformers
open.  Have you looked at the specs for a UTC A-19 or Essex/Stancor A-4774.
Might be able to find one of those if they will work.

Let me know what you find out.

One of the two modulator interstage transformers (T102 or T103) in my HT-37
has an open primary winding. Has anyone discovered a workable substitution
transformer from the current manufacturers. My guess is obtaining an
original is very unlikely since you probably wont find them used anywhere
else. I see a few single tube plate to single or PP grid  transformers from
Hammond available at the antique radio supply sources on the Internet and
was wondering if anyone had tried one of those.
Looking for help,
Duane, KF4ZS
