"Centifolia"

OK, what am I missing?


** Wait for it.


My Sumiko, which is a high output MC, has an output of 3mV times a gain of
600 is 1.8V.



** The output may be 3mV - but at 1 kHz !!!

At 25 Hz it will be only 0.3 mV - due to the RIAA recording curve.

A phono preamp needs at least 1000 times gain at low frequencies -
even when no NFB is used - much more if it is.
