For one deck a rubber belt of the right section is no longer made — one was ordered custom.
The belt in a belt drive is the part that ages first: rubber hardens and begins to slip. Substitutes match in length but not in section, and then the speed drifts.
Tkachenko had a belt made to the original dimensions. He says it cost more than the deck itself, bought in pieces — but without it the turntable would have stayed an object rather than an instrument.
