Just an FYI/followup. No one sells a 'kit' for this particular model. I pulled the chassis out and cataloged a bunch of the caps, I'll post a list after I organize it a bit better. However, it appears the adjustment pot for my blue bias is busted, I'd like to find a schematic for this chassis so I can figure out a suitable replacement, since it doesn't seem to be obviously marked.
Any pointers there?
