Default Cartridges...again

A ceramic cartridge needs a very high impedance load (at least 1Meg) if
it is going into an unequalised input. A simple op-amp unity gain
buffer using a FET input amp (even a TL071 will do) should make things a
lot better.


Yes. I think you'd find difficulty in buying a ready made pre-amp for a
ceramic cartridge these days. Not that I'm sure anyone would want to -
although there was a time when it was thought they might be a way forward.
The BBC once used them on one of their turntables - probably designed in
the '50s. The cart was an ACOS - can't remember the model. Then there was
the Decca Deram.
