FelixSpeedGThe left channel isn't dead. It's just fussy. It's a common problem, but oddly hard to research. The only fix I have found is changing tubes. Some tubes that work 100% in another amp just don't play correctly in the Ocean. The left channel will be muffled, garbled or fade in and out. Changing tubes eventually works. I am sure there is a mod that helps, but I don't understand caps, resistors, circuits, or electricity.
