Dual 1219 Shell connection

Dual 1219 Shell connection


I'm troubleshooting a Dual 1219 with a Stanton 681 EEE Calibration
Standard cartridge. Lastmtime I used it a few months ago, it seemed
fine. Now, the sound is stereo, but tinny, thin and lacking low end.
Cleaning contacts and re-seating cartridge in its shell changed
nothing. I cannot see how the contact is made between the four pins on
the mounting shell and the tone arm. Can anyone help?

That doesn't sound like a mechanical problem.
Sounds like the phono EQ isn't doing its job.
If you have another amp, try it there. It
would at least rule one or the other out.

Hello,

First, make sure that you have the turntable connected to a phono
input, as the cartridge needs proper EQ and gain. The RCA cables that
Dual provided are always suspect, though they are more likely to cause
hum issues than anything else. If you are unsure, replace them.

The 4 pins on the head shell contact something like a circuit board at
the back of the arm shell. Clean them with alcohol, Don't use abrasives
on it. The crimp connections on the head shell wires themselves can be
trouble too, and they are no fun to resolder.

The Stanton cartridges rarely fail, but make sure the stylus is clean,
and fully inserted into the cartridge body.

Best of Luck,

Thanks.

I have good L/R channel balance and signal continuity throughout the
chain. Before I try another amp, to what degree do you feel that the
connection quality at the 4 pins on the head shell, the RCA cable
connections at the turntable and the preamp, or the cable itself could
affect the low end of the frequency spectrum?

Donstaff,

Not that great a chance. Did you conform that the amp/preamp/receiver
you are using has a phono input? Are you using it with the same one
that you used several months ago?
