From what I have read here a difference of around 20v between V1a and V1b plate voltage is normal. 
I am reading a 28v difference V1a 206 and V1b 178.
I am going to double check the cathode resistor values later, is it worth trying to get these voltages closer, I can't find the post but someone mentioned 200v as a target for a sweeter tonal spot
thanks in advance
