Hello. Some of you may remember my post a while back ("K200 thump") about my K200-A5 PA head. I finally saved enough cash and worked up enough pride to bring it in to my local music store and have it tuned up. I figured that since it's about 35 years old, it couldn't hurt; i think the power caps on it were starting to go, and I depend on this amp, so I figured why not. I should have back within a week and i'll keep you guys posted if you're interested. Thanks!
