We were kicking around the concept that the phono section should be at
the turntable instead of the preamp, indeed, if you have a stereo amp
with volume control you shouldn't need a preamp, but also because the
phono section should be close, very close, to the cartridge, as with a
tube or FET condenser mic.

Theoretically this is a good idea. Certainly it reduces the length of cable
carrying the low level signal from the cartridge. In practice, however,
most all the pickup problems occur in the cartridge coils, not the
connecting wire.

Not really. I have seen many, many cases where a serious hum problem
was corrected by dealing with the wiring.

IOW, you are solving a non-problem, and spending money to
do it.

So why is a built-in preamp so common in radio station turntables? Because
radio stations don't have phono preamps built in to their consoles.

True. Which is why I did it -- my premap does not have a phono
input.

They
have mike preamps, but these don't have the necessary RIAA compensation.
