Did you clip one end loose to check them? ('Specially the high value ones. The 3.3K ones not so much.)

I checked the plate voltages of V125, the 12BH7 R-Y/G-Y demodulator:

pin 1: 33v
pin 6: 16v
The 16V is 'waay low, less than half the expected. What about the grid voltages (pins 2 and 7)? Both expect the same, about -20V.
