From: Patent Tactics, George Brock-Nannestad
it is my pleasure to have found the official announcement (well, it was
actually made public in May at the AES Convention in Vienna, Austria) of the
crowning of an effort that has taken several years:
AESSC 78 RPM CALIBRATION DISC SET
AES Standards provides a rare opportunity to calibrate playback
equipment for 78 rpm coarse-groove records. Recognizing an international
need for calibration tools, the AES Standards Working Group on Transfer
Technologies (SC-03-02) initiated a project to calibration playback
equipment for coarse-groove 78 rpm records. The result is now available
as a boxed set of two identical 12-inch vinyl discs, catalogue number
AES-S001-064. The two discs allow one to be used as a day-to-day working
tool while the other may be stored as a master reference.
For more information or to purchase this set please go to:
It contains a re-issue from an original negative of a 1950s coarse groove
test record to the IEC standard (leased from EMI) as well as a freshly cut 78
rpm test record. The supplies are limited, but as we all know, once the
metalwork is in order more batches may be pressed up. AES has borne the
investment of administrative time, printing and boxing, and the work has been
pro bono - as usual in archive circles.
The sale of the records is extremely influenced by the use of steel needles
in your soundbox: the more you use them, the more test records you will need,
because the surfaces are ruined at an extreme rate. This is good for sales.
