A friend gave me an Alesis Spitfire guitar amp that died on him. The output finals went in it and blew the power supply fuse. I bought two new transistors tip31c and tip32c (npn/pnp) and replaced them. I can turn the amp on now and it does not blow the fuse, however, there is no sound. I am beginning to wonder if the output transistors took out a driver or something too. The people at Alesis were kind enough to give me a service document that has schematics and a parts list, so I am attaching the schem. of the main amp board. Based on this schem, which transistors do you think could have gone with the outputs? If I had to guess I would say the c2235 and A965, but I don't know, I havn't taken the advanced circuits courses yet... Oh, when you turn it way up you can faintly hear it play.
Thanks,
