Today we are using a set of alignment cassettes to check operation of a Marantz SD420 cassette deck.
We can test tape speed, wow & flutter, head azimuth and playback levels.
Tapes from:

** UPDATE ** Adjusted playback level on preset control RJ44 to bring the right channel up by the less than 1dB which was required.
