Here, I have pulled out all of these RCA tubes and some parts that I set aside from other groups of tubes I have bought because of the idems within the group and also tubes I switched/replaced with a Philco tube. Many still testing good and feel all could be. Don’t want them sitting around when they could be used. Will pack nicely for shipping with pics as I do. And feel free to make an offer. Hoping to be something well visited, I will answer questions if asked see pic’s. Thanks Will be doing a group of Sylvania if this goes well.
