Good on your findings. Sounds like we can zero in on the oscillator.
I would bring in the following subjects for questioning...
Part #5 - .0014 cap
Part #10 - 6k resistor
I also wouldn't rule a out a high-R open in the OSC coil p/n #12.
I'm somewhat confused about the relationship between trimmer p/n #11 and the adjustment numbers in the alignment instructions. If you have a better handle than I do on the physical layout of the set that trimmer might have some effect on the ability to oscillate.
