It is a modular TV for teaching, I am pretty sure of that. Every component is mounted on a small board that is easily removed or replaced to, my guess, simulate a fault for trouble shooting practice. I would really like to find some documentation on it but so far no luck. The tuner and IF strip are right out of a Predicta setup and as I dig further I may find more similarities. It does have a push pull audio output stage that uses 6AQ5 tubes.
I have tried digging through all of the Philco TV schematics I have trying to find something similar but so far nothing. There is one module that has a broken tube so no idea what the tube would have been, will have to try to figure out what the circuit is, my guess at this point something in the sound circuit.
