I was running amp on sideband and first key it smoked. Turned off and unfortunately no repair techs anywhere near me. Only thing I can make out on cap is 100v. This is right at the input coil. What do I need to check other than this and probability of bad transistors from fireworks?

    Does anyone know if you can replace the 2290 in a galaxy dx 93t twin turbine with a 2sc2879 red dot? If so, what would have to be tuned?
