Azimuth Alignment Audio Cassette

Description

If your cassette deck sounds great when playing its own tapes but sounds muffled or unclear when playing tapes made on other machines, it's likely that the record/play head(s) are out of alignment.
With the use of this special azimuth alignment cassette you can quickly and accurately re-align your deck’s head(s).
Best of all, unlike other more expensive alignment cassettes, no expensive test equipment is needed with the use of this cassette.
All you need is a “mono” switch on your receiver, amplifier, or preamplifier.
If you don’t have such a switch, you only need a Y-adapter cable (not included) such as this one: http://www.amazon.com/C2G-Cables-Stereo-Female-Y-Cable/dp/B0002J1LE8/ref=sr_1_2?ie=UTF8&qid=1448639176&sr=8-2&keywords=stereo-to-mono+rca+audio+adapter
The cassette is new but not sealed and it comes with step-by-step instructions.
