Hi, I am experiencing a very important issue with my flextone III During the last 30 days it just restarts... first I thought maybe it was the power cable and it doesnt connect well. Tried a different cable but the problem persists... Yesterday it stayed off for some time before it could power again. When I turned down the switch the normal sound on the back clicked, if this does help, and after a while I could power the amp again. I now dont know what to do, I use this amp for gigs and I dont what this to happen during a show... I was lucky enough that it didnt happened on my last gig a couple of weeks ago!
