Jim, I really liked the C7. In 1982, it was the best that I could afford...a straight wire with a gain control. As far as I know, there is nothing wrong with the it. I don't have a turntable anymore...the ex got it (Rega Planar with a Grace 707). I got the C7 and the Acoustat TNT-200. Sad to say that I don't need these pieces anymore and would like to find a good home for them. And no, I'm not a broker, just an old audio tweek who's investing in making music rather than listening.
Wind Chaser, I did read the guidelines. If I made a faux pas, please forgive me. I would like to sell the C7 and seek a fair price. I don't know what the market price is. I've seen the range from $350 for a toasted unit up to $800 recently. I live near the San Francisco Bay area.
I welcome any advise or offers.
