Telematic Tuner Subber Schematic

[DaveCT]

Just picked up a Telematic combination tuner subber/crosshatch generator at a flea market and it doesn't have either a manual or a schematic. It works, but the crosshatch generator has a couple of burned resistors on its board that I'd like to replace. Does anyone by any chance have a schematic or manual for this puppy? Unfortunately, I don't see a model number anywhere on this unit, but it's a very simple one: VHF tuner on the left front, UHF tuner in the middle, and slide switches on the right front for power and generator function. There's also a "gain" pot on the bottom right front. BTW, the generator output is either dots or crosshatch and is advertised on the front as "digital."

Any help would be appreciated!
