Questions: 
1. Is part 40 the capacitor across the primary?  I have a new .03 (1.6KV) cap.

2.  If I find an exact replacement 32-7019 output trans I know to just wire it EXACTLY like the original. I know the original speaker voice coil is 1 ohm RESISTANCE.
If I buy a replacement output transformer of the same dimensions and KEEP the original speaker (1 ohm), how would I choose the primary/secondary values?   I cannot use 7K/4 or 8 ohms if I'm keeping the original 1 ohm speaker. 

3.  I see the 1140 ohm field coil (hum buck, etc) in series with the output T (open 400ohm terminal 1 & 2).  How would I take this into account when choosing/connecting a NEW replacement output transformer? Piggyback the new one on top of the 32-7019 and series connect the 1140 ohm section?       I don't have a deep understanding of the theory.   I need some answer like "choose this XX value of output transformer instead, and connect wires 1,2 & 3 like this ____.  Or buy 2 different parts, one XX impedance to replace part 37, and one output transformer of XX value. 

4. The output tube is 6F6G, it won't change. Capacitor 40 is .03 (will it need to change if I use a different transformer & speaker?)

Assume I have no knowledge of theory.   Appreciate the responses but some is above my head.
