I wish to thank you guys for the help.
I called Pioneer and they informed me that the pick-up was the only way to
get the cable.
I replaced the pick-up and now it almost works correctly.
I think it has something to do with the focus and tracking pots.
This is probably a stupid question as I know some are quite familiar with
these set-ups.
Now for the BIG question....how do you do the set-ups?
Thanks,
Daryl
