Guitar Amp repair in Baton Rouge

Searched and the last thread I found was from 2017 so I figured we could use a new one.

I was strumming yesterday for about an hour and set my guitar on my bed to take a phone call. I didnt switch the amp to standby and about 3 minutes into my phone call I heard a loud POP and now have very low volume with high static. No experience with amps other than replacing speakers so I need someone that knows more than me to diagnose it. I've used Live Music on Florida before and they were good, it just took them 2 months to fix my issue last time so I was seeing if there was anyone around here specializing in amp repair.

Amp in question is a 76/77 Music Man 2x10 HD130
