I seem to have lost my way on this PT-6.
I see the antenna aerial transformer schematic - I’m reading pins 1 through 4 counterclockwise with a cap connected to 1, pin 2 connected to the chassis, pin 3 connected to 7C6, and a wire going from the tuning condenser to the 7A8, and the antenna leads going to pins 1 and 2 on the coil. Also a wire underneath the tuning cap going to the oscillator transformer.
I think I have this totally confused - does anyone have a good picture showing where the antenna leads etc go?
After attaching an outside antenna and checking the connections against the schematic -and realizing two were reversed - I now get loud volume and a rushing noise - no stations.. As the only tube I haven’t replaced with a known good tube is the 7C6 detector - I’m thinking that might be the problem. New one on order.
