grid impedence of paralleled tubes in push pull
 
When connecting the tubes in parallel is the impedence z\number of tubes or does it not change the z. Is there a formula for finding this?

Also push pull is the input signal to the 2 sides 180 degrees from each other but twice the signal input?

Paralleling reduces impedance. It also increases capacitance.

Yes

I guess what i'm really getting at is how do you figuare the z because I was thinking it's not just finding the capacitance reactance of the grid at the lowst or highest frequency.
