comments:
"I understand some bias meters are made for AC tube filaments. My amp is home hi fi and uses DC filament current. Is your Bias meter right for me?"
Paul 01-19-07
"Absolutely.......
Our Bias Meter has none of those limitations and has nothing to do with the Filaments. It is a straight through connection on all pins except for the current sensing resistor on the Cathode. The unit itself is powered by a standard 9v transistor battery. It powers up automatically when the probes are attached and even has a sleep mode to save battery power when the Plate Voltage falls to a low (~10v) level. It even wakes back up when the Plate Voltage is restored."
