After reviewing your voltages I don't think your lo is running. The control grid of the 6A7 should read about -4v or so not +42. Recheck 10 and 11 for proper value and measure the resistance from pin 5 of 6A7 to the osc coil pin with the resistor on it. Should read a low resistance like 20ohms.

Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
