Thanks for your reply zoomer. Both transistors look pretty fried, and the one crumbled when I touched it. Its hard to say if the signal became grounded or if it saw 12 volts because that darn metal plate on my amp around the inputs may have been touching some +strands of wire or even the positive ends of the fuses. I don't like the design of that amp at all. When I get some spare time I will try removing them, and see if I get sound back! Thanks for your help.
