Transformer (trafo) broken on primary circuit.
Amplifier has been left switched on for many days and suddenly stopped working.
All electronic is fine.
All I want is know the place where can I buy new transformer, or place where can I fix it.

Are you an experienced tech? In most cases (unless there is a defect in manufacturing) transformers are not a common cause for failure. If it blows the fuse disconnect the secondaries and see if it still blows the fuse. If it does then the transformer is likely the cause, if the fuse doesn't blow then the problem is elsewhere. If you have 120vac at the primary and nothing(or very low) at the secondary(s) then the transformer could also be at fault. If you have done this already and narrowed it down to the transformer, sorry I cannot help. I used service Samson but no longer am able to get parts. Good luck!
If the transformer is still in the mixer you should be able to trace out the primary by using an ohm meter or continuity tester. connect the meter to one side of the power connector and probe the leads on the transformer til you get a hit mark that wire and continue until you get another hit and that is the other primary.
If its a transformer based Amplifier you can rewind the primary winding for 230Volt. But it has to be done by a transformer specialist. All one has to do is unwind the primary on a winding machine and make a note of the number of turnings in the coil. Then wind back twice the number of turns using half the thickness of the wire that was used for 110v. Eg: if the there were 1000 turns of 20 swg wire in the 110 circuit when you rewind you have to use 40swg wire and wind 2000 turns on the bobin.
The only simple way that I could think of is for you to purchase a STEP DOWN TRANSFORMER rated at 500 watt, 110 volts, 60cycle. The transformer inside that amplifier have four output 12v and 15v DC.2amps It will be hard to get the transformer for that!
Hope that might help you!
my friend resistors and diodes don't just go off your circuit without a real problem. those parts gave up because of shortage on your power section, i suggest that you check your power transistros first along with the diodes and resistors.
noisy transformers... hmmmm why is that making sound? the solution there is to dip the power transformer to a thick shellac varnish let it there for let's say an hour then let it dry for a day. then place it back in your unit and see if still sounds
