Default Phono preamp RESOLVED - thanks to all who helped!

Well some ceramics were not at all bad. The deram for one.

Of course I'd imagine it would be easy enough to make a little amp for the
magnetic cart and match it to the high impedence input of the sharp. I'm a
little perplexed though why the Sharp did not hum like mad with nothing
connected at all.

Whenever I try to mate two or more pieces of equipment that
were not originally made for one another, I have a problem
with grounds. You should attempt to get the schematics of
both pieces of equipment, and make sure the grounding of
both pieces is compatible.


From my experience, ground is ground, plus no one here will even
realize the old ceramic cart housing did NOT come with the Sony
tt. *IF* it ever gets to that.

Anyway - problem resolved. The ****ing BSR cartridge is ceramic.
I had forgotten such things were ever manufactured.

(I saved the cartridge before destroying the BSR tt, and just
tested it. Sigh. Perfect. For finger on needle, NG for playing
/records/ of course... Cart comes with a (5th) ground wire.)

So now I have to buy a new stylus, and figure out how to attach
the BSR cart housing to a Sony tt arm. Or not, and just use it
as a super cool retro AM/line in system.

Thanks to all who helped!

I have 0 experience with ceramic carts. but the Sharp seems to
be a VERY well built unit overall. I would choose it, AS IS,
over /anything/ under $150 made today.
