If your B+ is normal and you have no reception inject audio at the grid of the first audio amp stage and see if you get anything at the speaker. If you get reasonably strong audio the problem is in the band switch, RF, converter, IF or detector stages, if you get no audio go over the audio stages. Divide and conquer.

I've changed the rectifier tube out for a known good 35W4 rectifier tube and it still wasn't working.
I'll take the chassis out of the cabinet and check out a few things in the radio's underbelly.
