Hi Folks, Don't know if anyone has done this before, but I thought I would see what happens. I have gobs of new 5654/6AK5W's. More then I will ever use. What I would like to do is trade some of them for 12SK7's. Anyone out there got a bunch of 12SK7's they want to get rid of, and need any 6AK5W's. 73 Jim K7SLI
