Checked the voltages - seem OK. Not right on the money but then I am using a variac plus a modern Fluke DMM, plus my speaker's field coil is 500 Ohm and not 1.5kOhm, so.....I don't sweat it, they are within the ballpark.

All coils are OK and the DC resistances are within reason to what the schematic names for them.

The 6A7 would be the easy usual suspect except somehow I feel that when I buy a new one it will behave the same. OK, will spend 10 bucks......
Sadly none of my other radios has a 6A7 in it; I do have a 6A8 but the pinout is different.

Oh, I even pulled a couple of stations around 10 MHz on the FBC, and one around 6.5MHz (where the oscillation does not work) which tells me one of the tubes was acting as an attenna all on its own.
