Amperex tubes questions

Thanks so much for the help. PS. To Dogpile, actually I am not sure whether it's A "frame" or "getter". I just use the word "getter" as that word was used to describe some of the amperex tube by some sellers. The labeled on the 7308 is mostly unreadable. So I could not confirm whether it has "USN-CEP" label. Once again, thanks so much |
