I would be guess in saying this is a RCA type tube with this type of internal structure:
 

 
They are the only ones that add that metal flap down the bottom. I have seen these with Chrome tops and clear tops, Black and Grey plates and top and bottom getters. I have seen them as RCA, Rogers, Sylvania, Tung-Sol and Raytheon. All the same tubes. There could be others.
 
My point is. They all hum in the WA22. Some very little. Some a lot. I have tried taking out the offending tube and swapping with a quiet. That doesn't help. I have learned to ignore this tube by a lot of purchases and tube rolling. Just leave this tube out of the WA22. Not a great sounding tube IMO. Your 7236 is far superior.

 
+1 .. agreed on all points, from my experiences with the WA3. I have TS and RCA versions and while I don't have the same hum problems, they are very middle-of-the-road in SQ. Many power tubes are better: TS 5998, TS 6520, TS / Sylvania 7236 and, of course, the holy-grail WE 421a. I just picked up another pair of TS 6520s - they sell for much less than others on the previous list and sound fantastic. Very underrated tube, IMO.

Good score on the 6520. One tube I would really like to try. What price approximately? And where from?

I have been searching.

Very nice dude. Both are cool kits.
 
Will you listen to their sound signatures? As you may be aware they all sound different. Technical accomplishments put aside.
 
For example:
 
My Oppo HA-1 is a fully balanced DAC. XLR outputs etc.....
My Arcam irDAC is technically very boring.
 
The Arcam DAC schiits all over the Oppo. The Oppo is cold and sounds like it was made in 1970 by a new audio company from some ass end of the earth. The Arcam is warm and musical and sounds like they have been making DAC's forever (Opps they have, they were the first to make a outboard DAC).
 
Gotta listen to them dude.

 

Thats not possible unfortunately for none of the gear im interested in,i always gotta go with what others think .Brands sold here seem to be different from whats sold in U.S. here you find more European brands   Audio GD products look interesting and they come with a 10 year warranty .The other problem over here these days is the currency exchange rate anything i buy in U.S funds i gotta add atleast 25%+ customs so trying to buy over here and used. its crazy 3-4 years ago our currency was on par with U.S. currency boy did it take a dive .C'est la vie.

Yeah. I know where ya are coming from. Same situation (I'm Kiwi (New Zealand)). We have to rely on reviews. I've read good comments about the first DAC (Wired4Sound). Read nothing about the second.
It is difficult. If ya read reviews on the net about the Oppo HA-1 you would get the impression that the DAC was the greatest built in the last 1000 years. In the end it was the worste I have heard out of the selection I have heard.

Badas you're a kiwi? Oh man shame about the WC Cricket loss. I grew up in Auckland but currently working in Indonesia.

There's a shop in Onehunga, sorry can't remember the name but it had some really good turntables, DACs and speaker amps. Nice owner to who was very helpful.

Yip. Auckland boy through and through. Was born here. Travelled the world and returned.

Turned on Audio is the shop.

I haven't had any dealings there but I should. Tony's WA5 was repaired there. As soon as I get a moment I will poke my head in and say hi.

You take care in Indonesia ya honorary Kiwi.

I was thinking about bringing my WA5 into an electronic store for a check up and maintenance.  Since I live in California it seem like a huge cost to ship to NY just for it.  Is this going to be a good idea or should I just send it to Woo to do it?

Big rap from me for these folks. Very helpful and knowledgeable. They are my preferred supplier and I have bought a lot of gear through them (Accuphase P-4200 / Simaudio 430HA ... etc).
 
The repair went very smoothly - great job and am very happy with the result.

My understanding from my WA5 repair is that the Woo amps are simple beasts - point to point wiring etc. A competent audio repair person is going to be all over them.
 
I live in NZ and shipment to New York was never an option  - so a local retailer put my repair out to a local specialist repair guy and he did a great job.
 
My 2 cents - if New York isn't close by I would be looking at a local repair option.

Feel you're pain, our dollar has dropped 25% against the US over the past year. I sent a PayPal payment this morning, (yep for more Tubes 

 and I got .73 cents to the US $.

Sorry for the delayed response... I was on vacation and promised my girlfriend I would (mostly) stay off the internet.
 
I find them from time-to-time on eBay; my tube guy in Madison, WI couldn't find any, but his collection is so huge there could be some in a drawer, undiscovered.
 
My last matched pair was $80.00 US - quite a bit less than the 5998 or 421a wallet-busters.

Holy crap, that's a pretty great price. I'd look around for more Power tubes, but I'm enjoying my 5998 too much.
 
Still waiting on my E88CCs, unfortunately, should be here early next week.
