Hi Jim and welcome,
I would check the 10k the 240k and the 1m resistor around the 36 detector tube. Measure the resistance from the grid cap to the chassis of the 36 should see abt 5m. If it's much higher it's time to pull the IF trans or drill out the rivets (3) on the shields and remove them to get the resistor. Do note that the plate voltage on the 36 det is abt 36v not 165v as listed on the diagram. There are two other possablties I can think of failing coils osc or ant, or a bad 36 tube.
Currently have an 80,81, bunch of 84's and 600. I Feel like I have fixed 100's of them vicariously on the net...

When my pals were reading comic books
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.

Now I think I've got!
