Excellent progeess. High plate voltage on the 7C6 triode may be a bad 36 resistor, s/b 470K. Also low current flow in the triode.

SW band oscillator probably isn't running. Check coil 18 for continuity pins 1 to 3 and caps 14 and 9.
Could be switch contacts too.

I'm hoping the new power supply caps bring the B+ down. You may have to insert a dropping resistor to take it down.

BTW - capacitor 21 with the choke coil wrapped around you can replace it with or without the coil.
