IIRC the Zenith tuners were in separate manuals with numbers
like TM or TS. I probably got the Sams, I will look tomorrow.
They almost always have all the different tuners, remotes, etc.
Sams are also a bit easier to work with, Sams are all drawn
the same where as factory manuals are all different.
Some of the Japanese ones are horrible..........
