Late post to an old thread, but here goes. This might be a silly question, but if you inherit a good vintage turntable that has been modified with RCA jacks in the plinth back, how do you tell which side is + and which - if the jacks look alike? Can you damage either the turntable or the pre-amp if the cables are are not connected correctly? Or does it matter as long as the ground wire is fastened firmly to the pre-amp? Best wishes. -Choppy
Captive turntable interconnects; should I modify??
Hi. I came across a NOS Denon DP47f turntable from the 80's. Purchased new in Japan by a serviceman & never opened until I got it. A lot to like; well-built, rosewood base, mint, never used condition. I installed a new Ortophon Samba low-output MC cartridge, and run it through a Perreaux SXVI phono preamp. I have nothing to compare it to, but it sounds wonderful in my system. One thing I don't like is the cheap-looking captive interconnects with "Radio Shack" style RCA connections. Will I realize a noticible sonic improvement by installing nice RCA connections on the rear plate and using a nice pair of interconnects? Another option is to hard-wire a relatively thin pair of interconnects directly to the turntable. Advice please. Thanks.
