Hughes & Kettner Statesman Dual EL34 Gold Pin Option

These amps are adjustable bias. If you use the HK shunt method all that's necessary is a Multimeter. A more accurate and far easier method is to use one of our octal bias probes with a Multimeter, or our all-in-one octal "Pro One" bias probes (which reads plate voltage and plate current simultaneously). These are available under the "Related Products" tab.

All tubes listed should bias up to between 32 to 38 mA per tube.
