Condition:
All cassettes are in good used condition. Several include original papers and handwritten technician markings/signatures. Some items have documentation, while others are cassette-only. The tapes have been stored carefully and show the expected signs of professional service use.

These are not ordinary audio cassettes but specialist calibration references produced for professional servicing and alignment of cassette equipment. They are increasingly difficult to find.

A unique opportunity for:

vintage audio technicians
cassette deck restorers
Philips equipment collectors
professional audio history collectors

Please study all photographs carefully for the exact condition and included documentation.

The cassettes are sold as a historical/service collection. Due to their age, calibration accuracy is not guaranteed unless professionally verified before use.
