The 36 tube was a bum design, even the Philco documentation suggests replacing the tube even if it tests good. I have had this experience with my model 14 LZX, it took an NOS 36 to get it to receive!

Later versions of the model 89/19 have a 77 tube for the oscillator, a much better design.

FYI Ron has a thread in this site that details how to replace your 36 tube oscillator with a 6A7.
