Well, open fuse or connection in your primary circuit.
Measure the continuity of the transformer primary (unplugged of course!).

i checked fuses and they are ok, i am not sure what is going on it was powering on last time i worked on it and from then it was not powered for 2 years
it only has 4 fuses and they all work. btw could it be because of the transistors i disconnected?
transformer is working there is sound like buzzing its normal but bulb is not glowing nothing blows up
Well, no initial bulb flash when you turn it on = no current draw to even charge the filter capacitor. You must have a disconnection between the transformer secondary and rectifiers or filter capacitor. Not unless the filter cap is totally open (odd).
Okay, you just posted that it works. Fantastic! Please edit your post to watch the language.

when i power it on and off with music i can hear that caps are slowly gouing out when powered off it is normal for those kind of amps, i had few transistor amps before and this is normal behavior
Yes, normal. No protection relay means the speakers are always connected.
You should turn the volume down to minimum when turning things on or off.

Great!
So you did hear some music?
And yes, 75W is a lot. Be happy that the bulb didn't light up 🙂

At low power I don't think you would see a glow. If the light bulb is glowing, your AC input voltage will be low. You can measure your AC input voltage to confirm.
