It is indeed a good good tube, but the more positive things we write about it here, the more expensive it is...Sounds amazing in Euphoria as well as in WA2. I don't get it. Such a cheap tube.

I have one that is stamped both, this is the same tube.Rca branded Chathams are very rare. Except for mine i have seen them only once...
Trying to figure out the date codes - 503 and C W. There is an RCA date code CW = April 1970. Don't know what 503 means; maybe 3rd week 1965?I have one that is stamped both, this is the same tube.
Good shot, but I think the tube was manufactured before HTTP existed…

434 JI doubt that CW is a date code. Typically, 503 would be the third week of 1955. And in that photo, to the left, I see a few more numbers, 434... ?

That is what is on the tube.
Tung Sol bought Chatham in the 1950's but I don't know which year. Possibly the RCA labeled tubes were bought from Chatham before Tung Sol bought them?A stab in the dark... Tung-Sol date: 1954, week 34. Sold to RCA and their date is usually a shipping date, so it was labeled and shipped out in 1955, week 3.
But sometimes it is best not to try to be too precise, so I would date it sometime between 1954 and 1955.
Yea... I was trying not to comment on itIt is indeed a good good tube, but the more positive things we write about it here, the more expensive it is...
It's close, but i prefer the clear top vs the chrome top.I remember reading somewhere that there are early cleartop RCA 6AS7G that are supposed to sound better than the regular and widely available silvertop RCA 6AS7G. Can anybody confirm this?
I don't have 421A's, but from the rest the best to my ears are for sure 6AS7G GECs.which is the most wide soundtage and holograhic sound among all the tube? 6AS7G, 6080, 5998 and 421A? i dont really like too warm as i've used to the Winged C 6h13C sound.
I read from somewhere else, someone said Winged C has wider soundstage than GEC 6AS7G. so i wondered does TS 5998 stage is wider/bigger?I don't have 421A's, but from the rest the best to my ears are for sure 6AS7G GECs.
Interesting note on this question might be, that Euphoria doesn't really have massive soundstage when compared to WA2.
Also I found the russian tubes to be quite weird, good bottom end but that was about it. And soundstage being quite small.
