Thanks to you both. Yes my intention was to:
Buy the manual
Measure the psus
Desolder and take notes of caps data.
Clean the boards. I will indeed put them in the dishwasher Jared. I would not have dared but now I will. How long that will take to dry I wonder?
Look with a magnifier at the traces.
Recap with Nichicon 105 deg low z caps. Good price when ordered by hundreds!
I understand the rom is a bios and I documented it in case the firmware was any use.
What is the frequency covering of the vco? From the L101 I'd guess GHz.
What makes you think I will have to replace it Jared?
Thanks,
