Philco model 18 (code 121) - HELP!

Sorry Pith but I guess I wasn't clear on the measurement across the two e-caps, I was looking for resistance. Might be easier to check from each to ground for some high DC voltages (power on). If you get good HV on the first one but nada on the second, it certainly looks like the choke has gone bye-bye. If you use the resistance scale at the same points as previously listed, across the + of the two caps (power off) you should get the value that Brenda suggested for a replacement resistor.
Your voltage measurement on the plate of the 78 certainly points to the choke being open.
Regards, Jerry
