Set up a sig genny and test him out


Much easier to say the test tape is stretched.
Perhaps perfect pitch testing would only work by playing the likes of JSB
Tocatta and Fugue in D major, not pure tones

How come I cannot google the rpm of an audio cassette capstan? A calibrated
strobe and tipex mark on the capstan periphery should give a definite answer
(assuming the spindle is clean and not worn).
It should be determinable from tape speed of 1 7/8 in per sec and spindle
diameter, that is about 1.9mm, but what should it be to 0.1 percent
accuracy?
