Collins 242F-5 trasmitter modulator power supply

[Opcom]

Does anyone have the schematic for the 'mod power supply' for the Collins 242F-5? I have one of these power supplies with little built in speech amp. Rather than disturb the orderly wiring, I would like to jack it up to operate it, so I need the diagram. It's a nice rack mount thing, maybe 10-12" tall and only about 8" deep, with 3B28's.

Needless to say it's not worth paying Fair's price just for the schematic on a piece of junque. I could not find it anywhere, otherwise.
