Goldmund Turntable with T3 arm--what is it worth?

I first thought you were referring to the one on eBay that is being offered by myostuff, but that has a Karat cartridge. The first thing you should check is which motor the TT has. If it's the Pabst, you should absolutely pass. Besides the fact that it has manual speed control through two potentiometers (in other words NO speed control ;~) the motor is a heartbreak waiting to happen. WHEN it fails, it cannot be repaired or replaced, and the quartz-lock JVC motor won't fit the older table -- plus you'd still have to find the printed circuit board controller and alter the old acrylic front panel to make it fit. Sooo, if the TT front panel has two little holes in it (on the right side) that say 33, and 45 (for the speed adjustment pots) you should pass. The T3 arm is OK, but not worth more that $1000 with a PL7 controller (they all say PL6 on the front, but PL-7 is stamped on the S/N plate on the back if it's a PL-7) The T3F arm is better built and holds its settings better, but worth about $1600 with a PL-7 controller. The table by itself with a JVC motor and a pristine dust cover is worth about $1600 - $1800. So $3200 - $3800 for the whole setup, with JVC motor, T-3F arm and all in great condition!
