I had Mackie th15a 110vac and it had busted fuse, when i replace it when a new one it got busted again...i plug the power cable to 110vac without a regulator. what would be the problem in the power section?

Almost certainly the amp has failed, as per usual with these, you need to take it to the repair shop and see if it's worth fixing it then sell it once working or for spares if not. Sadly whilst Mackie make some really good kit their powered speakers are not amongst the most reliable
