Dear Friends
Also have the same doubt. My tube amp at startup raises the tension to ~410V for about 20 seconds, then after the tubes start to conduct and lowers to lets say 190V. Do you PPL thing it is safe to use a K75-10 250Volts 50hz/AC here? Some say it�s times 1.4 the tention AC to DC, other say it even can go to times 2.4(???scary).
Tnx
Jo�o
