I had a similar problem with the 660L. It ended up being a bad tube socket (one of the 42 output tubes). Ungrounding the filter cans may give you a clue. Also removing the mounting screw from the bakelite blocks to unground them my help too. Seems like the issue is in the HV. If you pull the 5Z3 and power it up with 120v ac all the other tube s light and dials lamps??

No the set will just hum but doesn't hurt any thing.

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.
