The alignment went as expected. IF cans were way off, like 445 kHz. After peaking them, fidelity on AM was better but not much louder.

The dummy antenna recommended for AM alignment was a .02 cap across terminals with generator connected to A and G as well.
I could pull in one of the few music stations; 740 AM from Toronto, which is AWOL some evenings. Volume is "polite" even at max and the tubes seem to run cool.

Dummy for SW band needed to be a 400 ohm resistor but I only had a 180, which did not seem to matter. The osc/ant adjustments made for better selectivity. The 25 meter and 49 meter bands seemed to open up as it got dark at 7.

This set is about as small as late-30s AC-sets come but it was easy and would be perfect at a desk or anywhere else you are no further than 5 feet away.

I have a '37 Zenith 5R125 tombstone like this and the wire antenna works best on the floor, putting it further from interference sources like the PC and other switch-mode hash sources.
