What's it worth?
I have a Thorens TD160 turntable with a Denon DL 103s moving coil cartridge, and a Mark Levinson JC1-ac moving coil cartridge preamplifier that I would like to sell. The items are in original packaging and are in tip top condition. I searched around a bit and found this site. You guys appear to be up on esoteric merchandise. I was hoping you could help me put a value on my old treasured equipment.
