I just acquired a SB 200... and the bandswitch is VERRY SLUGGISH.. I'm thinking Mr. Previous owner may have sprayed something in there ..... I have various "cleaners" some with silicon...some from caig, but am wary to put anything on that switch. maybe it's just the detent ?? If it is not the detent , what stuff is appropriate to "ungooy" the bandswitch contacts ?? tnx bill ny9h
