I suppose I should have noted on my cassettes failing with age comment of several days ago, that my cassette deck is a Nak 680ZX, which does have the 3 head monitoring feature - However, I fear that mechanical failure of cassettes is an inherent problem with the cassette medium and even good decks have the problem. Also, I'd like to reiterate that there are only two safe head cleaners to use on tape deck heads - isopropyl alcohol and Freon TF. Any other compound like the Audiotex solution can damage tape head encapsulants. V Bill Mitchell CSO Whippany, NJ (whuxj!wjm)

RE: head cleaners.
isopropyl alcohol seems to work fine for tape machine cleaning.
however, don't use garden-variety rubbing alcohol, as it is only about 70%
pure and contains ingredients to make it gentle on your skin
(read OILS --these can cause slipping).
look for the 91% variety, which is carried in drug stores but is often
hard to find. a friend's cassette deck had slipping belt problems and
repeated cleaning with rubbing alcohol only fixed it temporarily. one
thorough cleaning with the 91% stuff cleared it up for good.
