For best results Mono pressings should be played with a Mono Cartridge.
Most mono cartridges are equipped with a dual set of output posts, which means that both inputs on a stereo preamplifier will receive the exact same signal, this will result in a "soundscape" thats portrayed exactly midway between the two speakers set up for stereo playback.
In my opinion there would be no need to alter a Stereo setup in any other way than to have for an example a tonearm with a detachable head shell, or removable arm wand like the Graham mentioned above, to facilitate an easy cartridge change between Mono and Stereo
Good Listening
