Cassette recorders

Friends:

	For what it's worth, I got curious about cassette speed variations when
I was a music teacher.  We had five cassette recorders in the
department.  I conducted some tests, recording A440 from a strobe on a
cassette and checking it on all the others.  
	If I recall correctly, not one of them matched any of the others.
Therefore, at most, only one could have been correct.  Which one?  Who
knows?  The _cassette_ may have been wrong.  For those few instances
where intonation was critical, I bought a variable speed cassette
recorder.
