Three (3) GEC KT66 vacuum tubes, used, no matches. These came from a pair of Quad II amps. One of the four tubes was bad, so I replaced the quad with new Russian tubes and I'm selling the remaining three British made tubes.
All three measure well and work fine under load. They do work great and sound very nice. The labels have worn down on two of them, but they are marked GEC, Genalex and Marconi. The one marked GEC has a missing guide pin and is coded "TF Z". The Marconi is the best looking.
These will be well packaged very well. I will ship ground within North America for free. Other methods will be at cost.
Please bid with confidence.
Kind regards,
Thomas
