just by random chance looking on eBay I spotted the right folder for the combo 221-6 which has the radio but does NOT match the TV chassis.
close, but has critical differences

221-6 is the one I have, so I could send you the Radio portion of the Sam's I have, and you could use the TV portion you have and you should be able to get by with those two.

No problem.

Im just curious, but what was different between your unit and what was in the Sam's Folder that was supposed to be for your unit as far as the TV section went?

I'm asking because if it was something like the tuner being a different unit than used in yours or a slightly different tube line-up than yours had but the overall circuit layout was the same then I would just use the Sam's for the combo unit and just note on the Sam's the differences (whether it be tube line-up differences or tuner difference or whatever) and you should be good to go.

I've had to do that plenty of times myself when I've worked on some of my old radios in my collection where there were some slight component differences from the service data I had on hand but the basic circuit layout was the same (my RCA 5T was one example) and all I had to do was just note on my service data that there were some slight production changes made to the unit between the time the service data was made and the time that my unit was made that didn't make it into the service data.

Differences in the voltage divider layout and filter caps used, slight diff in Vert & horz out circuit.
Video out also different, 6AH6 VS 6CB6.
And yes, tuner is different,
just slight changes all over, enough to be annoying! :P

OK, that's what I thought, basically just some minor production changes that were probably made after the Sam's was produced and they never released an update, which was very common back then.

Which I agree is very annoying, but we have to work with what we have, just like they did in the old days.
