Hey, i am always getting screwed with gear, i dont know WHAT happened this time. i just got my rig back from where i was keeping it at. i get home, and find out that if i turn the "tube drive" Knob more than 3 the PEAK light flashes wildly. my limiter light doesnt even flash, just that stinkin red PEAK LIGHT! i dont understand....do i need a new pre amp tube? its a tube/soilid state hybrid type deal. and yes the limiter is on.
