Not exactly a glowing recommendation... I'm going to try to find a pair of RCA 6AS7G. But, first I'll evaluate the stock tubes. Shipping estimate is next week, so I'll probably have it the week after.

Installed a very nice NOS pair of Philips Miniwatt EZ80 tubes. Call it placebo, but the background seems quiet and the bass goes just that little deeper than with the stock rectifiers

 

[Skylab]

I doubt it is placebo. Rectifier tubes absolutely have an impact on sound, and I bet those are nice tubes

Me too, at first I thought changing the rectifier tubes would have a bigger impact than the power tubes.

Did anyone try this tube in the wa2?

Winged "C" 6H13C / 6AS7G

 

[Skylab]

I haven't tried it in the WA2, but in other 6AS7G amps, the Russian 6H13C has not sounded nearly as good, to me, as even the RCA, which can easily be had cheap.

After spending a couple of days looking for tubes (this is my first time, and there are so many numbers and brands, I really think it's a jungle out there!), I'm not even sure how much I care, if they are cheap. Just want them to be good. Everyone around here praises the Tung-Sol 5998, but they are hard to find.

Skylab (or others), can you recommend me an internet tube shop, where I can pay with VISA, and where I might find these RCA's?

 

[Drag0n]

Saving for a WA2......Hope he makes this amp for a long time and tubes stay available.
Im hoping jan/feb order.

Would anyone care to recommend some 6x4 rectifiers?

 

[Skylab]

I am generally partial to Sylvania black-plates.

Woo is now shipping Sylvania 7236 in place of the 5998. I ordered a pair yesterday.

 

[pzm9pzm9]

I once ordered Tungsol 7236 from WooAudio, but they turned out to be defective within one day. So they sent me new one but this time Sylvania 7236. I liked Tungsol 7236 little better than Sylvania for having little more full body sounding. And the red printing on Tungsol was beautiful! But the SQ difference was small I didn't care to send them back for Tungsol. Jack liked Sylvania 7236 more than Tungsol when I asked him in e-mail. I also have asked Skylab and he liked Tungsol more, like I did.
But in the end, I think Tungsol 5998 is THE tube to use for the full body sounding. If you own WA2 you gotta try Tungsol 5998!!!

 

[Skylab]

The 5998 is a MUCH better sounding tube than the 7236, IMO. But among 7236's, I do indeed like the Tung-Sol better.

 

[pzm9pzm9]

I really won't know what to do if my set of 5998 dies... It is so hard to find matched pair!
Speaking of matched tubes, do we only need matched tubes for power tubes? I am trying to get a pair of EZ80, but I am not sure if they need to be matched. any help?

I guess I kind of lucked out as my WooToo arrived with a pair of TungSol 5998s, philips jan 6922s & GE Jan 6x4 (6202 USA).

Any recommendations as to where to roll from here bearing in mind this is an early WooToo if that makes any difference.
