[Heathkit] Setting the Bias

[Daniel Yoder]

Thank you for the clarification.  With cathode current, unless the final
amplifier tube(s) is / are triodes, you have to subtract the screen current
to get the actual plate current.
So since my finals are beam pentodes the cathode and plate current would
not be the same value?
Are my finals a push-pull in parallel?
Thanks for the help
