Meantime, I decided to fire the radio up. With 80 tube in place of 5Z3. First I measured the HV transformer output, was fine, so I inserted the 80 in, checked the B+, was fine, let it warm up, touched the 1st AF grid, heard the buzz, tuned the BC band into the local station; first nothing, then I remember the AVC switch, flipped it,....the station came through. Not as strong as I expected, though with a short screwdriver touching the antenna clip it became very loud.

Well, maybe it will be it for today....perhaps I will order the 5Z3.
