blank pcb,s can any one id these please

I suspect it is a push pull amp and here's my lunchtime interpretation of the circuit. The area in the green block I suspect could be some form of resistor module as there isn't a resistor from V1 grid to ground tracked in.

I've also forgotten to put the pentode suppressor grids in but they are connected to the cathodes.

Any ideas which record palyer it would have been fitted to?
