There are two slight variants - a top getter and a bottom getter. The picture from this EBay auction is great because there is one of each - top getter on right, bottom getter on left.

Pair of Tung-sol 5998/421A Tubes *2 - eBay (item 390033166335 end time Mar-24-09 18:52:57 PDT)

I have some of each and there is no sonic difference that I can tell.

Otherwise, there are no variants.

The elusive ECC230. It is difficult to find even photos online but John Hupse has one (Philips). Note the AJ type code and the R factory code; i.e., according to the code lists, 6080, Mullard/Mitcham, which is exactly what The National Valve Museum shows us. ECC230 (Mullard) and 6080 are listed as equivalents in the Vademecum.

The 1958 Philips ECC230 datasheet tells us that "this type is interchangeable with type 6080" while the 1960 and 1968 datasheets just call the tube 6080. It would seem that ECC230 was Philips-speak for 6080 and that they soon reverted to 6080.

Has anybody seen ECC230s other than the Philips/Mullard 6080 kind?

Funny you should mention that - I discovered I have a pair like this when I was looking at my 5998's yesterday. A but unusual it seems, but there they are!

Yep - there seem to be quite a few like that. I like the bottom (only) getter best in terms of looks, but I think they all sound the same.

 

[glitch39]

i've listened to both O and D getters in both side and bottom locations.

No difference in sound.

Skylab, regarding the Ultron 6AS7G that you have sometimes written about (your photo), don't you think that they might be Svetlana-made? This Ultron was a house brand of Bürklin; they did not make the tubes themselves.

 

[Skylab]

I am almost certain that they were Svetlanas, in spite of the fact they were labeled "Made In Germany". Some people love the Svetlanas, but I have never really dug them.

I have a pair of 6AS7G's that say "Amperex - Made in Holland", and are in Amperex boxes. Pretty sure they are Svetlanas too.

And I have seen Telefunken branded 6AS7G's that some poor SOB paid $100 for that were definitely Svetlanas.

 

[Oskari]

Incidentally, I just received my first Svetlanas. First impression is that the 6N13S aka 6H13C betters at least many a shrill-sounding 6080 (in DV336SE). These were more like $9 each including p&p. No fancy branding, just =C=.

 

[Skylab]

I think the winged C could be considered fancy branding

I have never heard a 6080 that I liked much, so your post does not surprise me at all.

All of the 6080's I tried sounded Flat, dark , and laidback. The epitome of un-exciting.

Ditto. I tried the Mullards, too - they were better than the US 6080's, but still an RCA 6AS7G blows them away.

I like the RCA 6AS7Gs. I also like the TS 5998s. I'm going to go back to the RCAs for a while, but I think it is possible I like them more than the 5998s.. Both are Great though. I have never had those GECs.
