I've put up a recently copied .wav file (coincidentally entitled "Wave, being the name of the tune) from a home recorded cassette here:

wave.wav

This is off a tape I made of 2 friends playing duet nylon-string guitars, recorded onto chrome cassette in my little home studio (very basic, built around a PA mixer and 4 PA mics), 29 years ago. Late last year they asked me if I could copy the tape to CD so here is one of the tracks, recorded using the Presonus/Reaper/Audacity chain described above, and using a mid price 30 year old Yamaha cassette deck for playback (my "better" deck having gone on the blink and may never work again - ah well.). I actually routed it through an analog mixer as well and added a little digital reverb (a 30 year old Alesis box) too. I think it sounds OK :)
