[Hallicrafters] SX-117 aftermath

[K9FFK]

Jeff:

I'm not happy about your misfortune with your rcvr, but I am curious 
about what happened. I have 2 of these rcvrs.

Do you have pictures of the IF transformers? Which transformers are they?

The AVC line is bypassed at V1 (RF) via .01uf, bypassed at V10B (AVC 
rect) via .02uf and T3 via .01 uf.

AVC doesn't go to the low IF.
