I inspect the thing, and I see that only one channel is faulting.. I got 24 V and the other is at 270 (supposed to be at 180-190V), I'll go try your tip poobah.
edit : Before I do this, I check the resistance from ground to plate of the triode, one side got 20 ohm the other got around 550 ohm... this is with all tube removed
reedit : I got aprox 600 ohm on pin 3-4 of the output tubes on one channel and I got aprox 100 ohm on the other channel... what the funk ? could it be the out put tranny ?.. but it`s brand new

It could be the output transformer, to check just disconnect the center tap of the transformer from the power supply and measure 3-4 to ground, should read open..
Double check each supply cap for short to gnd as well.
Check to make sure no solder blob on sockets to chassis, this happened to someone I know. Almost invisible string down side of socket..

I`ll try this tomorow kevinkr, for now, I saw that when I switch the output tranny B+ wire from a B+ of one channel to the other, the reading from the ground to the B+ of each channel was inverted... one got aprox 600ohm and the other got 20 ohm but the invert, I start to think I got a bad output tranny...
