That's the filter choke in the power supply #28. Have the caps inside the metal can on top of the chassis been replaced w/film caps? If not this can cause that choke some thermal discomfort.
I would suspect that choke should measure several hundred ohms but it does have that a cap in parallel with it. Cap could be shorted. If it's arcing back to the core you could try insulating it from the chassis.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
