Here is one of my wiring schematic questions for anyone willing to look at the schematic.
The grid cap wire was gone from the 12k7 tube ,which should be wired to the 1st I.F. trans. 95-696 BA.
I pulled the can off to expose the coil a**'y, and there are 4 wire terminals.
Looking from the back of the chassis, there is a gray and a red on the left side(gray is far left corner).
Other side is a gray in the far right corner and a blue in the lower right corner.
Looking at the schematic, I can't tell which of the terminals on the left side the grid cap wire goes to.
I think it would be the gray in the far left corner, which if you follow the wire underneath the chassis it goes to a small coil.
Am I right on this?
Thanks
