AK Model 42 Transformer Ground?

[Winky Dink]

Whoops! I didn't notice that I had the coupling tube pulled. All of the above is without the coupling tube.

When I inserted the coupling tube it reverted to original--only three strong stations with no control from the volume rheostat.

I do have the modern schematic, but I learned to read schematics from Riders Vol 1-3, so the old ones are easier for me. They're more pictorial.
