Did someone have experienced or heard about the GEC CV 2523 ? What's the difference with the A 1834 ?

 

[Didege]

Sorry, another question : one write good things about the Tungsol 5998. And what about the "normal" 6AS7G ?

 

[Skylab]

You mean the Tung-Sol 6AS7G? I find them to be excellent, but they are not as good as the 5998.

Yes, that's what i meant, thank you.
Would you recommand it to fit with my Audiotailor Jade if i want a smooth but detailed and 3D sound while listening to ECM jazz ? And wich 12AX7 would you choose to "mate" well ?
Thanks in advance for your wise advice !

Detailed and 3D sound will be helped a lot by a Mullard CV4004 for the 12AX7 - but expect to pay $100 for this tube. A second place here would be a black-plate Sylvania 5751 (still not cheap, but cheaper than a CV4004).

As for the power tube, try to get a 5998, but if you can't, a Tung-Sol or Chatham 6AS7G is a good choice. But even the RCA 6AS7G, which is easy to get and very cheap, is a good sounding tube.

Waouw CV 4004 ... isn't it like shooting the moon? ... but i'll try...
I have a Chatham and it gives me a lot of pleasure.
You've written that all 5998 are in fact Tung-Sol; so if i find a National Union, shoud i go for it ? What would be a reasonable price for it ?

 

[Skylab]

I'd be shocked if you find a National Union branded 5998 - but as long as it is the "ST"/coke bottle shaped 5998, that is Tung-Sol made for sure. I have seen them branded Chatham, IBM, and of course Western Electric

 

[rosgr63]

Who makes the ITT branded 6080WB?

 

[Skylab]

No idea on that.

Sorry, my mistake : it's the 5751 that is branded National (probably a RCA ?)
I have the opportunity to buy a 5998 branded Tung Sol and CTL (in place of JAN or JHS) Do you know what it means and worth it 60$ (!) ?

Can you share your source for TS 5998 that sells for $60? ( assuming it's pair price).

I'd like to stock a few more.

This is a site in Turkey www.nostube.com, send an email to Koray Kural to ask for what you want because there is only a little part of their stock on the web !
I was asking about the price of this particular 5998 because i've just bought 3 of them on another turkish site (Adisa Service und Entwicklungs AG) for 3 $ each ! Turkey seems to become the place to be for tube rolling , isn't it ?

I've received three "new" 5998. Tough Skylab said that they're all made by Tung Sol, i didn't expect them to be so different :

- the United Electron has bottom halo and D getters
- the Chatham has top halo and the getters are quite hides but i think they're D or square
- the Tung Sol is the more surprising ; it has two halos and two O getters : one on the top and the other a round on the bottom side.

What are those configurations supposed to improve in sound ?
I've listened to the Tung Sol with National badged 5751 an it was great : i now really like the "SS" output, the guitar intro on IQ's "Frequency" is less harsh (less distorted in fact than with my Amperex BB + AS7G Chatham); very nice, deep but detailed basses ...

I have a doubt on the United : though it has bottom halo, i see a kind of another one (a sort of inside silver shadow) on the bottom. I haven't still dared to fix it on the amp. Have you an opinion about that?
