Check the voltages on the following pins J807, J808, J809, J810, J811. I guess you said everything was working before recapping the PS. If that is the case then you must have done some mistakes in your work so check your work very well. A nice picture of the PS board will be helpful too.

Hello,
Here are the mesurements with a dim bulb:
J807: 25.6v
J808: -25.1v
J809: 18.44v
J810: -13.33v

What is the wattage of the bulb you are using? Is it dimming completely after a few seconds of switching it on? If you think there is no short, measure the voltages at all those pins including J811.

Hello, problem solved!! Took out the Q801 transistor to mesure it and has bad readings, replaced with a 2SC2690 (lucky i've got some) and no more hum, also replaced the Q802 to a 2SC1845.
I really dont remember the wattage of my bulb, think it is near 40w, it dont dim completely with that amp but there isn't a short anywhere. Also checked the voltages without the bulb and they were near the values of the Service Manual, thank you very much Sanjib for your help.
However there's still the physical HUM from inside the amp wich i can't determine if it comes from the Power transformer, the big caps or the power amp section...
Please, excuse my poor english.

Physical hum is going to be the power transformer. Try screwing it down tighter.

Congrats!
Regarding physical hum try what @EastPoint suggested.
