After installing and connecting the freshly restuffed electrolytic cans, I cleaned, then reinstalled the off-on-tone switch.
The bakelite block containing the line-to-ground caps also went back into place.
I replaced the remaining capacitor on the right side of the chassis, a 0.22 uF which is connected between the cathode of the IF amp tube (6K7G) and ground.
A 700 ohm resistor in parallel with this cap turned out to be a problem. I did not have any 700 ohm resistors. So I improvised...I used a 200 ohm and 510 ohm resistor in series to end up with 710 ohms, close enough.
I also spliced new wires to the shadowmeter, rebuilt the shadowmeter lamp socket, and connected new wires to the shadowmeter lamp.
Now, other than attaching the power cord and taking care of two or three minor odds and ends, I believe the main chassis is finished!
