On 2009-12-15, JRF wrote to us, saying:
"The supply of cassette tapes has dwindled down to a few Wow & Flutter plus some 6.3kHz Azimuth tapes. We will most likely run out some time in early 2010. We have been trying to find a new source, however, so far it has been a dead-end search. We will let you know if something materializes."
If you happen to find other Cassette Calibration Tape manufacturers, send us a message and we'll add them to this list.
