echo sounds + choppy distortion- hartke a100
 

Hi guys, my hartkdm amp is outputting echos and distorted sounds. I plug in the amp to the mixer via xlr out, no problem. I plug the speaker to my guitar amp also no problem. i also tried few basses.

Has anyone encountered this problem before? Surely it must be poweramp section? Wondering if the fix would be pricey, since its out of warranty

>Thanks in advance

found out the problem. just need to re-solder components will "move" especially capacitors.
