• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.

Could this become a Baby Huey killer ?

The primary inductance defines a reactance wich must be equal to the reflected impedance at the frequency where you accept -3dB gain.

Thanks!
Now it is clear to me! Until now nowhere I could find this so straight and simle writen.

Note that the method suggested to measure primary inductance is nothing else that measuring the primary reactance at 50 Hz then converting it in inductance ( because 314 in the formula IS 2 * pi * 50) !

Yess! Now it is also clear to me! Thanks!:)

Could you tell me (suggest me) how many Btotal would be good for a toroid iron? (The niceest would be if your OPT DA could calculate with toroid iron........)
