Be 100 deluxe issue

[mniel8195]

Hey guys I recently noticed an issue with the switching on my be 100 deluxe. I thought it was the foot switch at first but I unplugged it. When I switch to the be channel he full signal is not coming through. After a bit it starts working again. At first I thought it was a Bad patch cable. But the hbe and plexi channel work just fine. I am running cables in the front of the amp and into the effects loop. I’m primarily using the amp with my suhr reactive load ir. Any ideas?

Plug straight in and see if it still has problems

Change the BE preamp tube. HBE and Plexi are separate tubes.

Agree with above. Go straight in and then add one thing at a time until you come across the issue.
