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.

What I wrote about Andy Karzas's comments concerning the pitch of  the Auer 
records can be explained by the following. Based upon my notes from the  

  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

Hello Don [Tait],

- 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,
