Findlasse

Hi!
Have been using the HX Effects for some years without any problems. It has started to shutdown after 15-20 min playing. It reboots but shuts down and reboot again. I power off after a while and then it runs again. And maybe doing the same after while maybe not. 
But - it is not usable for rehearsing or gigging as it now.
Using a 1spot supply from the first day I got the HX.
Anyone having the same issue? 
Guess it has to go to the repairman.
