I have two PT-6 chassis. On both there is a blue wire that runs from the above chassis transformer to pin 6 of 7C6. So the wire is there connected wrong at the transformer - which would be one problem. As I look at the original picture I took the blue wire from 7C6 it seems to go to a pin - pin 2??
I think my confusion here is not understanding the numbering sequence. I’m reading the pins - looking from the side of chassis towards the tubes as 1 being on the top left and going clockwise. With the cap in the photo attached at 1.  I’m not interpreting the diagram on the schematic with the pin numbers correctly I think. Pins 1 and 2 could be 180 degrees opposite.

I’ll draw myself a pic based on your answer and see if I can visualize the schematic better.  Thanks.
