P.S: Although I doubt it would happen, it’s possible that running your Shelter cartridge with the PH-10’s gain set to 71 db might result in distortion on musical peaks, due to an overload condition in either its circuitry or in the circuitry in the 2170 that precedes its volume control mechanism. If that were to happen, though, the resulting distortion should be pretty obvious, and would be present even at relatively low settings of the volume control. As I said I doubt that would occur, but if it does you could perform the experiment just with the 65 and/or 68 db settings instead.
