Thanks, but the 800BT has a projection TV (

Scott combined the 800B radio with a few different TVs.
I'm looking for a schematic that matches my TV, which has a 12" CRT and three chassis as described in the original post. Some folks have suggested looking at Dumont . . . or manufacturers located not too far from Chicago.
