I have two tentec Triton IV rigs. One is the analog model, the other digital. Both have matching power supplies and manuals. Both work fantastic. The top of the Digital rig is slightly marred, each has one non stock knob (but pretty close). I'd like to swap them on a Corsair II or maybe an OMNI V, other interesting rig...or I'd sell either or both. 73 de dave in NH
