Strange circuit- especially when someone in the past miswires it.
The volume pot not only controls the input signal but also some of the cathode biasing- turns out that the pot was missing it's center tap ground.
It's still not the best radio, but for a cheap 1932 superhet it's OK. Most likely I'll be eBay'ing it soon since I'm running out of room with all these big models in the way: 116B's, 640, 645, 650, 91, 70, 118, .........
