Cassette recorders

[Alan W Deverell]

Calibration Cassettes for checking and adjusting Standard Audio
Cassettes Recorders and players should be readily available with
standard test tones. You do however need something to measure the
pitch/frequency of the output from your recorder (a Frequency
Meter/Timer Counter - some of us electronics types have in our
workshops). All you have trained ears and with a tuning fork should be
able to tweak for zero-beat.
