Question about Audio Players & Recorders
Lightning storm, turned all equipment off and now amplifier will not power back on. I am thinking possibly a fuse. I do not want to mess with anything inside until advised from someone who has seen this before. I have tried other power cables as well, that does not seem to be the problem. I am hoping this is something I can resolve with my own hands, so I learn something in the process. Thank you for your help.
Most of the problems with the AVT 150 amp blowing fuses have to do with the TDA7293 power amplifier IC being shorted. If you have good solder skills this and a new fuse will probably take care of the problem. If you do not have good mechinical / solder skills, take it to a Marshall authorized repair station.

I would go ahead and take it apart, after you unplug it or course. if there is fuse on the back there will be one just off the ac line inside. These amps have an 12ax7 tube in them I beleive ,and large filter capacitors in them where voltage could be stored for a time after you unplug it ,but this is a fairly modern amp with bleeder resistors so it will be safe . you can wait over night to be safe, anyway you won't go touching the large capacitors anyway you are just changing a fuse. look for something like 2 amp or 5 amp in value. replace it with the same value.
