Notes:
Issued over 3 different releases #1 [r=4478405 #2 [r=6970239 #3 [r=1410902 Includes two four-page inserts (one titled "Technical Notes For Engineers" and another which is a reference for other CBS test records). The labels have a few typos where numbers with a “thousand separator” are displayed with a period “.” instead of a comma “,” (i.e. 20,000 is errantly displayed as 20.000). These have been corrected in the Tracklist for A1, A7 and B3. The runouts (on both sides) contain no etchings (except for a single stroke mark on Side B). The text (on the sleeve and insert) use the international “Hz” unit to denote audio frequencies while the labels, instead, use the older (and obsolete) “CPS” unit. Stereophonic Frequency Test Record
