I’ve been playing my mono LP’s the last couple days by installing my dedicated mono cart (and headshell) to my Jelco 850 arm.
So it’s a benefit of a tonearm with removable headshell. But without this option of your Jelco on SOTA turntable (that can’t accommodate second tonearm) it will be a nighmare to swap a cartridge on a tonearm without removable headshell each time you want to play a MONO LP with dedicated mono cart.
