Deutsche Grammophon 3D Classics Series Audio Cassette

This is another of the highly attractive, abundantly classy and sonically spectacular Polydor / Deutsche Grammophon CrO2 pre-records of the 1980s. It’s part of the 3D Classics series, which was released around the cusp of the ‘80s and ‘90s decades, with this particular instalment hitting the shops in 1989.

Rare 1983 TDK Records Audio Cassette Hybrid

Early 1970s Scotch Dynarange C-120 Audio Tape

I was quite flippant about the performance when I posted a photo of a Scotch Dynarange C-90 in 2012, but it’s often very hard with old tapes to evaluate them properly, since so little is known about the recording conditions, and there’s little or no space to record new sequences for test purposes.

Gladly, however, I’ve now unearthed an early ‘70s Scotch Dynarange C-120 with plenty of blank space on Side B, so I set about establishing what these 40+ year-old stalwarts are like when it comes to preserving a known quality of signal.
