Have a Sansui FR3060 that will only output on one channel.
I've put an ohm meter on all cables and connections and they
are reading correctly. The needle and cartridge appear to be
original equipment. Could the cartridge/needle be the
what's causing the single channel output. BTW I've checked
it on two diffferent amps same problem on both.

It's possible for a cartridge to have a bad channel (usually an open coil
internally) but a wiring problem of some sort is much more likely. You can
often measure DC resistance right through the cartridge coils right there at
the phono plugs - just measure across them. If they measure a short,
however, then the turntable has a shorting switch inside when the player is
stopped, and you'd have to "trick" the player by pulling it's power cord
while the arm is in the play position.

Mark,

Thanks for the information. The problem actually
turned out to to be a bad spot in the left channel
cable which is being replaced this weekend. Thanks again
for the help.
