thank you for your offer Jim,
but unfortunately I live in Italy (and I'm a newbie in this field). I don't think that the problem is only the selenium rectifier. I hoped it was so, and I already removed it and replaced it with two 1N4007 diodes with the two positives (band) tied together going to the to the C3 capacitor and the two wires from the power transformer to going the two remaining sides of the Y (it as a three wires rectifier and I read on the Asylum that it can be replaced this way). The hum was still here. No more tests made. Just tested all the tubes with my emission tube tster. They seem still good, no shorts, no leakage and they are still in the "good" range.
