Default strange Stromberg Carlson

I recently picked up an old film projector made by Kodak. The amp inside was made by "Stromberg Carlson, Rochester, NY." I am familiar with their later & more common equipment, but this is a different animal. It's clearly a 40s/50s design, using 6L7 6J5 3x 6V6 and a 5z4 metal tube. Pots seem to indicate 1958/1959. There is an interstage transformer and output transformer potted together in a large rectangular box. The design fairly reeks of RCA stuff, lots of multi-megohm resistor networks and magnetics. The tone control seems to be involved in a feedback network. Feedback wraps around interstage, and OPT. Local feedback to screens on power tubes.

Does anyone have any schematics for the Kodak FS-10-N, or same-era Stromberg-Carlson equipment? The build quality is extreme, I'd like to keep this thing as is (minus the photo pickup).
