Yamaha GT 2000 with 40 pound copper platter.

As I mentioned on this forum once before, if you visit the audiophile salons in Tokyo, the 2000 GT is one of the most common of the high end turntables that you will find for sale, in secondhand condition of course. Conversely, I have never seen a GT 2000X for sale. They generally command more than twice the price of a nice 2000 GT, if you can find one at all. There was an optional gunmetal platter for these tables that weighed 18 kg, which is even more than the platter on the SP 10 Mark III. So I have no doubt that the 2000 can handle a 40 pound platter without much trouble for the motor.

GT - isn't that 'gigantic and terrific!'?

Almost correct. I feel that they named the series incorrectly. They called them Gigantic and Tremendous. The series should have been named The Satisfier. That is more apt.

And I keep reversing the alphanumeric designation.  Toyota made a sports car in the 60s that they called the "2000GT". It's now very valuable to collectors. The Yamaha tt is "GT2000" or GT2000X.  Sorry for any confusion.

Toyota badged the car that Yamaha made and called it the 2000GT.
