cyto Posted December 15, 2019 Share Posted December 15, 2019 I bought this matched quad of JJ 6CA7 from a tube dealer about one year ago or less. I put them in my amp for 2 or 3 hours to verify that they worked and then put them up in my tube storage closet. I am thinning out some tubes and decided to sell these. $60 shipped in the continental USA. PayPal only. Thanks Quote Link to comment Share on other sites More sharing options...
