It's working kind of backwards isn't it? It should have an open eye with no signal and a closed eye on a strong station. I'm not sure which 1 meg you changed out, but I would put it back in and compare results.
For some reason your AVC is way too low. Did you actually peak the IF's? J is the padder that you adjust the low end of the dial to. How about your 6H6 tube? I'd re-verifiy R6 & 7 and swap in a different 6H6 and double check the 1M resistor in the eye socket between pins 2 & 4.
After all of that, I think I'd stick the 6U5 or 6T5 back in and see what voltages you read on pin 3 with a strong station vs no station with about a 10' antenna.
