ALL ...UPDATE: I just swapped the XXl tube and the 7A4 tube and now radio works. The tubes are supposed to be the same? I get signals on all bands. Weak but I do have them. used sig gen to test the FM band. The calibration on dial is way off too. needs alignment. Next step.

Both tubes tested good on my tube tester.

Only reason I switched was the XXL tube is the RF amp. and the 7A4 tube is use mainly for the phone and driver to the 7c5 output tubes.
