  • Vintage Cartridge Confusion Debunked
    YOUR COMMON VINTAGE CARTRIDGE QUESTIONS ANSWERED by Bob Amos Mono Only Cartridge V Mono Stereo Compatible Cartridge – And Important Difference Many Dansettes you will see for sale privately and all too frequently by dealers also are sold with their original ‘mono only’ cartridges in place. The issue here is that mono only cartridges were only ever made to play mono records. Stereo recordings followed and started to develop greater traction progressively throughout the sixties. Mono records require the stylus to track only the sides of the groove (lateral compliancy), whereas stereo encoded records require the stylus to track the groove both laterally and vertically - it is this that produces the two separate LH and RH channels for that spatial stereo effect. It therefore follows that a mono only cartridge with limited vertical compliancy is liable to damage your stereo record. For obvious reasons it also cannot resolve properly any musical detail encoded requiring vertical deflections. BSR (TC8) mono only cartridge example - not suitable for stereo records Every player that we sell or restore is fitted with either a mono cartridge that is stereo compatible or a full stereo cartridge correctly configured for mono reproduction (left & right-hand channels commoned together in parallel). Why crystal cartridge selection is important Other important observations that frequently arise relates to the crystal pick-up cartridge technology that is needed to drive the valve amplifier topology incorporated in these vintage players. Why a vintage ‘single-stage’ valve amplifier requires a high output crystal cartridge To keep manufacturing costs down, budget entry level players of this era were commonly fitted with a very simple, single stage valve amplifier.
