I'm sure you're right in saying each board is an amplifier. I would expect the o/p valve to be nearest the o/p transformer.

You could select a likely looking candidate as the grid coupling capacitor, connect a test lead to one end and then with the meter on ohms scale probe round the valveholders looking for a very low resistance. Repeat for the other end of the capacitor. It should be connected from anode of one valve to the grid of the other.
