What is this PHA SYM ADJ on my Rev Blue. I did a google searched and could not find anything.

It's a phase inverter symmetry adjustment knob. Bogner reccommends only touching it with a scope. You won't hear much tweaking it by your ears. It does have a visible change on an O scope though. I wouldn't worry about it.
