Yes those who have been reading my posts know that I've been quoting Brent Jessee several times before. It also says Brent Jessee in the text so I'm not claiming it to be my own text. Not all tubes have visible factory codes I know, but for what I know also at least some of american Amperexes should have codes. What I'm trying to say is that there are lots of beginners out here and it's important that they know how to interpret codes and look for them. If tubes are not identified by codes you should at least tell people about the triodes, getters, supports, shields etc. I wouldn't encourage beginners to buy expensive tubes based only on painted text even though many of the best tubes might only have such. If Coil has room for improvement in his expression of thoughts so does you. Lets not try to constantly troll or diss people about their impressions or opinions.
Opinions and freedom of expression I can agree with you on. And teaching newbies, I agree on. But certain people tend to speak in absolutes and when that occurs, then "newbies" get confused. That is the problem I have with the post's value.
If they were posted as "If you can, try to find an etched date code - most European made tubes have them - to determine the actual tube date and manufacturer"...Then I would have no problem and agree. But picture some newbie thinking he has a false tube because there is no etched code. He may have an American made tube or a European tube that did not use it.
That is all I am saying. It is valuable that you provide and help interpret those codes. And if Coil wants to help people great. Just use caution on the absolutes. Caps are another subject. He had a bad experience with his Panasonics so now, no one should use them. I did and mine sound awesome - and did require break in. Yet, I did not post - NO you are wrong, they do sound good. He posts in such a way that people will never use them. He forgets that much of this is system dependent and power caps really don't hold that much sway in SQ.
Anyway, I will be on my best but don't rush to defense if I call something out. I too want to help newbies and don't want them misled. In many ways this thread has really gotten too long. You too have seen new posters say they cannot get through all the pages ....Perhaps some updates to the FAQ pages ? Just a thought..Opinion
