okay, when you switch from SS to tube rectification, the hum change, it is more electric on SS and more warm on tube, but the problem is still there.
all the resistors on the filter give the good value.

It was the first time i was power it up since the modification where i have change most of the wiring for shielded wire. Before the mod everything was working fine exept for the squeal that he was making with some guitar with vintage type or pickup.

I will try to redo all the test to be sure i did not make a mistake and mislead you on the diagnostic, ill be back with that tomorrow morning, thank you for your time, it is very much appreciated
