I found the problem. I have found when something goes wrong, take a look at the last thing you have done, even if it seems to be totally unrelated. While working on the chassis, the rectifier tube fell out of its socket. I plugged it back in and had nearly forgotten about it. Looking at the rectifier, I noticed it was turned 90 degrees from where it should be. Apparently sometime in the past, someone had forced the tube into the socket with the wrong orientation. wallowing one of the small holes. Now the tube can be plugged in two ways with little effort. of corse, I plugged it in the wrong way. This caused one end of the filament to be connected to HV winding of the transformer. The other end of the filament was connected to the B+ line, putting high voltage AC on the filter capacitors. After correctly installing the rectifier, I replaced both filter capacitors.

Ok, "Smoke Test",  Take-Two

I powered it up again. No smoke.   I have a Sony headphone radio I keep in the shop just for checking oscillators. The radio has a digital display, so I can tell the exact frequency. I put the headphone radio on and started rocking the dial on the 19. Success! No stations, but I have an oscillator. The oscillator was running about 200KC low. I did an alignment on the oscillator and the front end and the "Super"19 began to sing!

Enough for today. More to come.
