Tube rolling with the Audiotailor Jade

[Skylab]

It's impossible to answer the question about the GEC vs Chatham in terms of gain, since (within a certain range of course), different tubes of the exact same make and type can have different gain. But the differences within a certain tube type don;t tend to be large. Of course the 5998 and 6AS7G are different tubes, with different gain factors, so that does come into play where the 5998 is concerned. However, the 5998 has MORE gain, so that it would have a higher level of distortion is counter-intuitive if distortion is indeed the issue here.

But in any case, who cares? You have a tube combo you like and that works for you - it's all good!

Thanks, Skylab. Yeah, I didn't think the GEC and Chatham would be that much different.

And I misspoke earlier, the impedance of the HD580 is 300ohm, not 200... but my point is still the same, that the imepedance of the 'phones makes a big difference in where you need to set the volume; in my case, the difference in volume setting between the K701 and HD580 is larger than it is when switching between either the 5998 and the other 6AS7G's, or the 12AX7 and 5751's. There are a lot of variables here...

Just curious guys, Is there a major difference between the Sylvania 5751 Grey Plates (much more affordable) and Black Plates?

Thanks!

I think it is just bos of the time of manufacturing and the stock now it have.

BTW, i am using the RCA 6AS7G with TKF 12AX7, it give a good performance. If i want to replace the RCA one, in order to give more analytical on listening strings, anyone suggestion can be achieve my goal?? Thanks

A Chatham.

If you can find one... As I mentioned above, I found that the GE/RCA was a little less detailed than the Chatham.

Take a look at this Sylvania 5751 thread, if you haven't already. I've wondered the same thing. There are multiple versions of the gray plate, though - some newer than others, and (presumably) not as good. The most famous gray plate version is the gold brand label with gold pins, but that's just as expensive as the blacks from what I saw when I was shopping around.

A T-S 5998 will be more analytical than the RCA. The RCA is a good sounding tube, but it is the LEAST analytical of any 6AS7G type-tube I have heard.

I have got this today

and it really sounds more detail than my RCA, at least now i can notice the breath of players in chamber music

Got my 5998s today, and I agree it does sound a lot more "thick" and darker than the chatham or RCA. Mine doesn't have the distortion or such as Pauly's, and mine has pretty good bass too. Less low detail than the chatham though. I'd say if you really want "tubey" the 5998 fits very well. I personally found the Chatham a bit bright at times, but it has great detail. I really can't decide which one I like better though, depends what I'm listening to

Got GEC 6AS7Gs now, they were incredibly expensive but worth the price. It just makes piano sound so realistic. It has an airy and balanced sound and it does something sweet with highs and mids. Detail seems to be on par with the Chatham and soundstage seems better. The Chathams sounded a bit bright to me but the GECs don't. The bass is a bit less than 5998s and doesn't sound as heavy as the 5998s, but it just does many things right to me. I can see why Skylab likes then, and speaking of which, thanks for the ebay link Rob

Those jumped out at me the first time I switched from TS5998 to the GEC.

My pleasure to assist

Glad you like 'em!

Yep, they do have a bit less bass than the 5998. But I do think they sound better. That must confound the few detractors I have around here who want to write me off an an inveterate bass-head

What output do you guys prefer with your current tube combo, yin or yang?

 

[bpj87]

Depends on my mood.
