MA50H Bias

What should the bias be set at for the MA50 Head?

35mA... atleast that's what mine was set from the factory with a 450v plate voltage. That's what a set my NOS tubes to and sounds like a million bucks....

Awesome, thanks!

Finally figured out that my plate voltage is 461. According to the bias calculator at tedweber.com, I set my bias at 37.9 Sounds awesome!
