Good Morning, I finally got around to testing all of the tubes in the R-390 and these are the ones I don't have on hand. Before I order them from a tube outlet online I thought I'd see if anyone has any extras they'd like to sell. I need: 3 - 6AJ5, 5 - 6BJ6, 4 - 12AU7, 1 - 6AK6 and 2 - 6082. Thanks, Rick/K5IZ
