[Hallicrafters] WTB: Power Transformer for TO Keyer

[Russ WQ3X]

Hi all -
I am looking for an original transformer for the HA-1 TO Keyer. Mine has
none (just gone, leaving behind some crispy-looking leads!) so even a bad
one would be fine because I could rewind it. According to the schematic,
there is no AC fuse?? Maybe they figured a really small fire wouldn't hurt
anything! There is black tarry goop all over the chassis where the
transformer used to be.
Thanks for any help,
