Screen grid I assume you mean the AVC line or do you mean the control grid. The AVC has a .047 on it.

I can see now that the cathode bypass resistor and caps for the 78 IF are missing with the cathode straight to ground. that's why the bakelite block is missing. There are four components that are missing
R43, C44a and C44b, and R45. The primary of the second IF connected straight to the b+

But they did leave the 5K resistor on the shadow meter.
