CBS LABS, Professional SQ Test Record SQT-1100

A laboratory quality disc, designed to completely test and evaluate SQ decoders.  It was intended for cartridge and decoder manufacturers to evaluate their SQ products.  It was also used by audio reviewers to accurately rate the decoding performance of SQ decoders.

Extra Bonus:

I also will provide to the winning bidder a scanned copy of the super rare 10 page booklet that came with the LP originally, this manual describes in detail each test cut on the record, and how to apply it to decoder analysis and evaluation.

(Complete 10 page scan of above booklet provided to winner in .ZIP format via their choice of EMAIL attachment or on floppy disc shipped with LP)

Very rare disc, never sold to the public in record stores, it was intended for professional use only.  This CBS Labs disc contains cuts to completely evaluate the performance of your SQ decoder, whether it is the original Logic style or the Tate system.  I don't recall ever seeing this LP for sale on eBay before, it is extremely rare, especially in NOS mint condition, and don't forget I am also including a copy of the rare instruction booklet that came with it back in 1973.  Album is in mint condition, looks unplayed, obtained directly from CBS Labs many years ago during a personal visit.  It will be well packed with cardboard stiffening and shipped promptly upon payment, with tracking numbers provided to the buyer.  Don't miss this chance to obtain a mint condition copy of this rarity for your Quad collection.
