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?

I don’t see any “physical” damage to anything else. I’m nervous about the transistors simply because I really paid up for this amp a couple weeks ago. Here’s a picture hopefully you can zoom in and give me the expert opinion. Thanks guys
 
I did unsolder the cap that’s why the coax is not soldered in. If it’s as simple as trying a new cap could someone post a link to what to get. I really appreciate the responses. Used to have a local tech that was good on everything I took him. Sure do miss ol Mickey Mouse being around.

    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?
