I have a Kenwood KD 2055 turntable that I just had tuned up, lubed, new belt, speed calibration and new RCA cords. The problem I'm having is when I play the turntable the volume is almost 50% lower than all of the other inputs such as CDs, FM, DVD and TV. I am running it through a Yamaha RX-V3900 with a PHONO input with the ground connected. It has a Shure V15 RS cartridge that may be old but not alot of hours on it and always stored in a/c along with a new stylus . Any suggestions? I'm trying to get setup to record vinyl to CDs and I'm a little new to all of this. Thx
