There's a guy in P'Cola that buys and sells vintage stereo equipment. I believe that he posts an listing on CraigsList sometime in the Electronics section.
I had a Dual back in the 60's and 70's, finally wore it out. I have an ION now, has the ability to plug into a computer and put the music in the computer. Not being a tech nerd I haven't learned how to do that. Just an analog man in a digital world.
