I used a pair of these when I built my very first 300B monos (overkill) about ten years ago.It's a heavy duty unit and has a 120V/240V primary, 380-320-55 (bias tap) -0-320-380 at 200mA, 6.3V at 3.5A for power and input tube filaments, as well as 5V at 3A for rectifier tubes and a 5VCT at 1.5A for a 300B filament. It is also noiseless (no faint hum or buzz. Good Luck, wpod
