Would anyone have a schematic to this box? It is an outboard PA used with the Messenger 202(?) for AM business band.

It is a nondescript large grey box, with a single 'sweep' tube final, built-in solid state modulator with heatsinks and two TO36 transistors on one end, and an octal socket for cabling to the exciter radio.

I have used it as a 10 meter Class C amp for FM, and have stripped out the modulator/xfmr. Just wondering how much drive it can handle -- I presume 5 watts.
