Big Band POLYTRON BB5510 Mati Total

If the Polytron BB5510 Big Band is completely dead, see the solution below. You may have the same problem. There are two shorted components on this Polytron Big Band: a diode and a MOSFET. The SR380 diode and the K7A65D MOSFET need to be replaced. I hope this information on how to repair the Polytron BB5510 Big Band is helpful.
