[Hallicrafters] HT-37 refurb/troubleshooting

[Al Parker]

Hi folks,
    I don't remember a separate fil. xfmr in there, so don't know where
the primary leads for it might be, but do remove the filament leads from
both pins of the rectifier socket(s) to totally remove HV from the fil.
windings.  You can see some info/pix, etc. on one of my webpages:
http://www.boatanchors.org/HT37.htm
    Those HT-32 & HT-37 power transformers definitely do have a bad
history of failure, usually the HV winding to 5v fil. winding, or one of
them to ground.  I've had 2 with the problem
