hey guys, so I just recieved my Spider Amp from my aunt, I accidentally plugged it into a 220v socket and the amplifier smoked, I plugged it back to 110v and I only hear a humming sound. What are the possible things to do in order to fix this? I had it checked to a technican and he said that the transistor was burnt, he asked me ,what is the transistor number, it was like TDA something but the rest of the letters are unreadable due to the burn. Hoping for some answers. Thanks!
