This has a heck of a lot more guts to it than the usual VCR RF modulator. Seven transformers/coils and four pots? Hard to imagine what that's for unless maybe this has a lower sideband suppression filter so it can be used in a master antenna system and not interfere with another source on channel 2.

Is there a frequency marking on the crystal in the lower right?
