I'm in total agreement. Get your money back and buy another before you DO regret it!
In reality, it only matters what it sounds like to YOU!!!

This usually would indicate that DC is present where it shouldn't be. Likely a bad blocking cap. If one's bad, then it's time for all of them to be replaced.

So with a little circuit knowledge, a volt meter and a less than a $5 cap, it might be fixed. On the other hand, whatever the going rate is for a shop to do a full run thru is the other end of the spectrum. Someone that's had that done could better put a price on that than I can, but what...probably $150-200?


PS...yes, you should be concerned about spkr damage!
I was there for the 10th Carverfest! Glad you were too! Or you should have been...
