CTC-16 Restoration

Could be with the phosphorus, I'm wouldn't be the one to know.

I was able to scope out the waveforms on the schematic in the surrounding areas. Maybe someone can catch something I'm not seeing.

Edit:
Photos don't seem to be appearing for me, if anyone else can let me know if they see them

Not able to seen the photos directly; I need to click in the "link", and input again the VK credentials, for each one.
LATE EDIT: after that, all the photos appeared in the post.

are these taken with a x10 probe and the scope not set for it? cause the SAMS has the beat pulses at the sync phase det at 90v, but it's WAY below that in your pic.

Yeah, good catch. 10X probe, forgot to plug it on the scope. Pk to Pk, 108v on the beat pulses. I was more checking for correct waveforms over voltages on my initial check
