A possible solution is: 1 Buy a tuning fork pitched at A440. 2 Get yourself a piano recording recorded on a modern piano, which is concert-pitched at A440. It would help you if the key of the piece is also in A, and also that it's slow. Such a recording might be the one by Sviatoslav Richter of Schubert's Sonata D. 664. Whether you like this or not isn't the point; which is rather that you can compare the relative pitches of your tuning fork and the piano, and use your ear, [or the ear of somebody good at these things such as a piano tuner], to adjust your turntable's speed. It might not be perfect to the highest standards of revolution, but if done accurately, it should be good enough to ensure pretty reasonable accuracy.
