A bit of a commercial plug here. We can and do fit 12" arms to the Technics SL-1200 to allow the playback of 16" records see www.78-rpm.com the parts are available separately and it's an easy DIY job.
We also do variable speed see http://www.soundhifi.com/images/HFW_Jan14%20Timestep%20RA.pdf
I will have an exhibition stand at the San Antonio ARSC Conference with both these items on demonstration.
At last years IASA conference Brian from "George Blood Audio" demonstrated an App called PitchLab that accurately measures singers voice pitch and allows easy correction by altering the turntable speed, very impressive. If the singer is in fact singing in tune then on one screen you get a consciously running set of lines that show where the voice is pitched, simply increment or decrement the speed to get the singers pitch to alighn with the correct note.

See you at San Antonio ?
