The moment of truth, Take 2.
Once again, I plugged the Zenith into the Variac.
I plugged my test speaker into the Zenith's speaker socket.
I also hooked up my longwire to the Zenith's A (antenna) terminal.
With the Variac off and plugged into the power strip, I turned the radio on. Then with the Variac set to zero, I turned the knob up slowly. At 90 volts, I could touch the grid cap of the 6F5G and get a solid hum through the speaker.
Well, that was an improvement.
I turned the Variac on up to 120 and...
NOTHING. (Again?)
I began to wiggle tubes. Wiggling/striking the 6K7G had a positive effect and the radio began to play. But if I turned the local-distance switch to LOCAL and back to DISTANCE, the radio would stop playing.
I finally coaxed it to play long enough to shoot this short video of it playing the local Spanish language station:

At least now we're making progress!
