Anybody know where I can get my LLano serviced?

I have a LLano trinity 300 that has some distortion in the right channel when playing music.There is also a ground loop hum in the right channel that goes away if the amp is grounded to the pre,grounding the amp does nothing for the distortion which is more like a clipping sound.

I would greatly appreciate it if somebody could point me in the direction of a tech that is familiar with the LLano amps.
If you're near the Dallas Fort Worth area I would get contact Freeman Tuell 214.324.1132. Marvins Electronics in Ft Worth would be my next choice. I've got two Llanos myself. A Trinity and a 100S. Good luck and happy listening.
