I have the (I think) current ordering information on my Web site at http://www.richardhess.com/tape/tips.htm But, to be honest, I find it more useful to play the tape on a four _channel_ 1/4-inch deck--I have a modified Otari MTR-12 that I use for this, but many of the Teac or Sony decks would work just as well. In fact, all of the track formats appear to have their own signature. Thanks for bringing this up! Cheers, Richard
