Hello, i aquired 2 KT66 tubes from another TGP member a few years ago as an added bonus from something i bought. Problem is, i have no use for them at all and i want to sell them. I have no idea if they work. They look good but... I dont know. They both came a 2 taped Ruby Tubes boxes that say matched, Anyway i can test them or about the worth of these things? I hate to just throw them out.
