Some special 6080? Never really looked into those. Would love to hear how those compare to well burned-in 5998's.

Btw, about those Chatham 6AS7G, I'm really impressed with what I'm hearing, at least from Euphoria, will try them in WA2 too in few days.

To be honest, I didn't expect much from those, I just thought... let me buy this so I don't have to keep burning 5998's when I'm just listening to music on background while working/playing something.

So now I'm slightly confused. Are all 6AS7G pretty good ? Or is this one type in particular amazing and rest is meh ?

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 am a little confused - you state that the first three are Chatham branded, but I only see Chatham, RCA and TS?

Sorry, i meant first three are all Chathams but they are branded as: Chatham, RCA and Tung Sol. The last one is RCA but it is branded as Tung Sol.

Corrected the post, hope it is clear now.

Chatham 6as7 is really good. You also have RCA 6as7 that are quite popular and not much liked as being quite warm. I like them but i like chathams much more.

Bendix 6080 with graphite plates (with holes) is one of the holy grails i think. I will have a chance to listen to them next week once i get them.

I don't want to write super hyped review, but these tubes in Euphoria with the PSVane 6SN7 drivers are really good for the money. Now hearing it I'd probably pay 200$ for pair and be very happy about the trade.

You mean RCA 6as7?

It is, yes. Is it for sale?

Earlier in this thread ( i think) someone, perhaps Stavros, mentioned there were at least 5 different Bendix 6080 variations.

No sorry, I mean the Chatham's I just got, that's what mordy was replying to.

No it's just pic I found on google from some sold auction.

Yep! Different plates, different micas, different getters, etc...

As always Similarly, when I look closely at my Chathams 6as7 not all are exactly the same. For example my tung sol branded Chathams seem a bit bigger than others.

If Chatham sold tubes branded RCA it seems to me that you should be able to pick up RCA branded Chathams for less than the going rate for Chathams. How can I identify them?

Good, luck sometimes happens chatham 6as7 have beautiful midrange.

Nice tubes You have. I think i will never be able to buy GEC 6as7.

Are chatham 2399 different to Tung Sol 5998? They look similar. I have TS 5998 branded Tung Sol and IBM. I would think chatham 2399 this is only a different branding of TS5998? I have seen chatham 5998 as well. But i may be wrong.

2399 is not a different kind of 5998. It is a truncated version of IBM's inventory number for the 5998.

IBM purchased tons of 5998 for use in their early computers. And in fact, IBM purchased so many of them, that Chatham / Tung Sol often put IBM's part number on these tubes: 3002399, or 2399 for short. Otherwise, they are just a 5998. Nothing special.

If they sound different, it is likely due to different dates of manufacture.

I have two pairs of clear top RCA 6AS7G's from 1951 (I believe that year is correct). Compared to my other RCA's, these have a bottom getter. They sound very nice, I love having a few pairs on hand and regularly roll them into my WA22.

I am sure that the year is correct, the early ones I have are from 1953 and 1954 and they are not cleartops.
