|Dave Harris||Re: Bias of Crate VC3112|
The AC30 runs with about 10V across the 50R common cathode resistor. That is a total of 200mA, 100mA per side or 50mA per tube. That is a lot of current and heat (about 65W). What was the original Crate bias ? The Crate transformers may not be able to provide the AC30 current.
