Notes:
Each complete test or group of test ends with a locked groove.
Intensive notes are found on the sleeve for each test, care of records, about this record and Ambisonics.
Although the sleeve states that 'The master disc was cut at Strawberry Mastering, London, on a Neumann lathe fitted with an Ortofon cutter head', Side A was in fact cut by Tape One, as evidenced by the runout etchings.
