Cool.

Thanks for info. Almost wasted $$ on 5998A.

Seamaster - you may want to try the 5998s - they probably have the impact you're looking for.

Yes those are the reasons I did not try 5998. Yes I may got the bass I want with 5998, but lost other good quality of the sound. I had too many RCAs, they are no where near as good as GEC.

Thanks for sharing guys

5998 isn't as rare as it said to be.. Most can be bought for less than $50.

GEC, on the other hand, is truly rare and equally expensive..

RCA 6AS7G is also almost as good TS 5998, and usually cheaper (usually 1/2 cost of 5998).

I got Syl 7236 coming, and I am currently bidding on 6AS7G and TS 5998 also.

^ Where can you get a matched pair for $50?

have you tried 5998 before?

5998 tube, Electronics. Great deals on eBay!

$50 was meant for a single tube, not a pair, BTW.

Also, I haven't tried 5998 myself. It was a reference from Skylab.

There is also the 5998 tube, made only by Tung-Sol regardless of branding, which does have different operating characteristics, and may or may not work in any given 6AS7G application, although it does in the amps I have, snd sounds a little better than most 6AS7G's. In general the 5998 offers slightly more neutral sound, slightly better transparency, and are less likely to be noisy. They are approximately 2-3x the price, generally, and I have seen some idiots paying $50 per tube on Ebay when you can buy them NOS from reputable online tube-sellers for $25 each. Still, this is more than double the 6AS7G price.

^ Thanks for the link.

But you would need a matched pair for the WA22.
Don't buy them from supra_buyer, it's Single Power (Mikhail Rotenberg)!

Most are rated within the 'matched' range.. But, yeah, thanks for letting me know about "ikhail" #*@#>.

I hate that guy with passion

Slowly going up the 6SN7 chain.

The Sylvania GTA have a more immediate presentation with extended highs. GE GTAs are much smoother ... to their detriment.

What can I say - I like it rough. =)

The Sylvania GTA seem to be a better match for the 5998s as well.

Sylvania GT are next.

Have you tried Ken Rad VT-231? Clear glass and smoke glass sound the same. They are very exciting tubes.

Not yet - I've got the following waiting to be rolled:

Sylvania GT
Tung-Sol GT "Mouse Ears"
Raytheon VT-231 (2 sets of different types of plate)
Sylvania "Bad Boys"

At this point I've exhaused my tube funds, however, supposedly Raytheons sound similar to Ken Rad.

Ken-rad that are made in 1940 and 1941s are hard to come by, and it is in smoke glass. It should have a better sounding than later clear glass type. But it 's also known to have some phonics..

BTW, what do you like from the list above? Let me guess, TS?

and prohibitively expensive to boot.

I havn't rolled any of those yet. I'll do them in order from first to last.

I was able to score one pair of TS 5998, thanks largely to Skylab!

Thanks again, Skylab.

Well my WA22 is in for a treat! I just sent the payment for an EML 5U4G Mesh, and yesterday I bought a pair of Tung Sol 6F8Gs from eBay. I'll let everyone know my initial impressions.
