53-1750 Problems when warmed up
#6

Two other ways to have a look at it are look closely at the clear plastic bottoms of the two transformers. W/the set and the light off you may see some flashing (arcing) inside the transformer. Another is to disconnect the B+ from the IF transformer's primary and listen to hear if the noise is gone.

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.
Circa 1966
Now I think I've got!
