Now this is just wrong. I found this tube in the pile of Chinese tubes that I keep because I can’t through them away (there is something about tubes that stop me from doing this) and nobody would buy them for any reasonable price. This is 12au7 that came with one of my amps. If you look at the metal divider that separates two plates you will see dirt on that divider. If you’ve dealt with NOS tube you know that they can be dusty and it’s hard to clean them without removing the silk screen. The same durst is present inside of the tube!!! Wholly Sh*****!
