Teaberry Stalker XX unstable carrier offset

[Lkaskel]

Hi Everyone,
I dusted the Stalker off the shelf and wanted to do a quick test before I worked on the clock. The it sounded strange on TX so I went through the alignment to check things. The PLL alignment was fine until I got to the final stage. The 7.8025 and 7.7975 were verys unstable. They oscillate high and low. I checked the voltage at TR21 and they were within a few 10th's of what specd'. Would anyone have some thoughts?

I am pretty sure whoever wrote the voltages for node 8 was smoking crack.

Two things come to mind. #1, a bad switching diode. #2 is something I have done, swapped crystal filters and had to adjust for the different filter bandwidth.
