[ARC5] RBB-6 Bring-Up

[Richard Knoppow]

    Use Deoxit Fader lube on the pots.
    Have a look at the switch decks to make sure they are in 
alignment with the rotor. I am not familiar with the switches in 
the RBB but most rotary switches are assembled with through bolts 
that are fastened at one end. If they get a little loose the 
decks can rotate a little. The other suggestion is to clean them 
very thoroughly. Even if you have already cleaned them do it 
again. Work the switch about twenty times and clean again.
