Hi All,
I have taken my 1219 Dual out of a closet with the intention of
recording a few hundred 33rpm records.
Mechanically it works fine but electrically is sems to be dead. The
connector on the end of the output wires was an
old antique, and the cord was looking doubtful, so I replaced it with
one that had two RCA connectors. I had to solder two spade connectors to
the wires to connect into the turntable socket.
I loaded a record and it went through all the correct mechanical motions
but there was no sound out. I connected the DUAL's 2 output wires to a
Sony amplifier
Which input ?
that had speakers attached - still no sound - and then
directly to the Audio In on the back of my computer - also no sound. I
connected the output wires of a tape unit first to the amplifier and
then to the rear of my computer and there was sound both times, so the
problems is with the turntable.
The output voltage from a magnetic cartridge is mere millivolts and has to
be boosted by a pre-amp that also amplifies the bass frequencies more than
the treble (RIAA equalisation).
Connecting it to a sound card or input on an amplifier that's not intended
for cartidges (the correct type is normally marked 'phono') will very likely
be virtually inaudible.
You need the right kind of amplifier or a pre-amp unit.
