No longer available - I got my Clear Tops and the other party said the 6DJ8 type tubes tested very good and is also very happy. I'll be going through some more "stuff" to trade so watch for my ads.
I have seven 6DJ8 type tubes that I don't need and have no way of testing. I got these along with some other gear I purchased from a home recording studio. I would like to trade all seven of the tubes for one used pair of fairly closely matched pair of RCA 12AU7 Clear Tops. Feeling Lucky? Drop me a line, I'm open to about anything.
