That solution was given to me also...drive it with a separate preamp. Great idea! What bothers me though...in my case, the amp worked perfectly last May...unplugged it and put it away...last week I turned it on and zippo, just the bars on the display! WTF! Never ever had an issue with this amp. Gigged regularly with it until a few years ago so now it gets very little use...so strange!

I’m having the exact same issue with my Bogner line 6 112… reseated all the connections but still have 8 black bars and no sound… I can tell the power amp is working but no controls work or is there any sound! Help!
