Gusser, I just checked your post, and it warms my heart that you share in my passion for the reel to reel. When I went back to those "you tube" links that I posted, it brought back so many wonderful memories; that was a time when so many good things were happening, and there were many stereo stores to listen and dream of new purchases.
I just got some brand new tape from ATR Magnetics, and I highly recommend it. The price keeps going up but that's life in the fast lane.
What amazes me is the fact that after recording select music, I can listen to it over and over, hearing something new each time.
