Here is your circuit. The PTO feeds the grid of V1B via R48. I think I would look at R48 first, then make some checks around V1.
Disclaimer: I have not been inside any TR4 in decades.

I connected the wires back up to the PTO and again no signals!
I then put the spectrum analyzer close to the PTO signal output to see if the signal was being loaded down and I still have signal output that tracks the PTO.
Out of curiosity I connected my working DD-103 to the jones connector and it reads 9Mhz.
