Hello my name is ***** ***** I am a certified technician. When you say "fuse goes off" do you mean it blows the new fuse? or is it not staying in the holder?

It blows the new fuse
Electronic Musical Instrument Expert: Ron Winston, Owner of Winston Electronics, Servicing music electronics for over 50 years replied 9 months ago

OK when you put in a new fuse and try to turn it on. Do you hear any sound at all from the speaker, "pop" "hum" "thump"?

first heard some noise.. later no noice
Electronic Musical Instrument Expert: Ron Winston, Owner of Winston Electronics, Servicing music electronics for over 50 years replied 9 months ago

OK here is where you are. If the fuse continues to blow there is a short somewhere in the unit that will have to be repaired. Normally it is either in the power supply or the amplifier. From past experience. If you hear no sound and the fuse blows it is in the power supply. If you hear a burst of noise, a pop, a hum, or any sound at all the short is in the power amplifier area. Normally in one of these units you do not troubleshoot to component level you replace the module that is bad.
