I would be very interested in learning how you would tweak a Technics to play at all the different "flavors" of speeds of early acoustic records.

Based upon my notes from the time. On August 1, 1983, I played the two Auer records when Andy was here. I played them using my Technics SP-15 turntable. It has an LED speed change display. Additionally, I have a chart devised by a WFMT engineer that lists the very small up- or down- SP-15 increments in rpm terms. When I reached -0.9 on the LED display, Andy said "stop." On the chart, that was 77.56 rpm. The 12" Auer record contains Tchaikovsky's "Melodie," Op. 42#3. We established (I don't remember how: it's been almost 29 years) that the key for that transcription is E-Flat. At -0.9, Andy said "stop." "Start it again." "All right. That's E-Flat." I also don't remember what we did about the Brahms. Don Tait From: Patent Tactics, George Brock-Nannestad Hello Don [Tait], you wrote: > The late Andy Karzas, who had absolute pitch, said the records play at > 77.56 rpm. > - alas, absolute pitch is worthless unless you know what his mother's piano was tuned to. In other words, an RPM is no good without a reference pitch, typically for a or c. If you have a number of records pitched by the late Andy Karzas, we may determine his internal reference by measuring up the records. I have tried to fit 77.56 into the discrete RPMs you get from a 60 Hz mains with a suitable number of bars in the stroboscope: it does not quite fit the one lower than 78.26, which would be 77.42. So his incredible precision must have been obtained in a different way. Personally, I would have thought 76 rpm would be the correct speed. Kind regards, George
