Feedback issue

Alright my first jtm-45 is done. I have runn into a problem. When I crank up the gain on channel one it does not feedback but it oscilates. It only happens on channel one as channel two has no issues. If I just plug a jumper between channel on and two it oscilates as well. Just random high pitched oscilating, no motorboating of any kind. I also I have a plexi50 that does this with everything cranked to 10.
