It's been a few days back, I didn't go back to find the post but someone  
wanted to know the formula for finding the plate impedance on a tube. For  
whomever it was, as I didn't see it ever get answered, I'll post it below.  
I almost overlooked it myself and forgot about it.

RP = EP / 1.8 X IP

1.8 = K factor for class AB1 (Changes with ZSAC)
RP = Plate Resistance
EP = Plate Voltage
IP = Plate Current
