Here is 2min 37 sec sample I've digitized from a reel recorded in 1964. The sample is a zipped WAV, 96 kHz 24 bit, 85 Mb in size. The tape was played back on the SONY TC-765 from 1977, that is sitting on my bench right now. Thankfully I have a very strong bench as this machine weights 27.5 kg (ouch!) . An amazing recorder, thought.
