Any thoughts on Ether C vs Ether Flow C with the 22? Thinking of adding closed back cans for the sake of marital harmony.

Hi folks,

The WA22 is my first tube amplifier, arrived on Wednesday. I ordered with the stock tubes, came with a Shuguang 274B, Philips Jan 6080 and GE 6SN7, smooth volume knob and balanced/unbalanced input selector switch. I`m using the Oppo HA-1 as a DAC, which was my first and previous desktop amplifier. I`m enjoying it very much. My only full-size cans are the HE560 and the ED8, both with balanced cabling. Didn`t like the ED8 driven from the WA22, though. But the HE560 is playing wonderfully, highs are not aggressive in some tracks as was the case with the Oppo. Detail and soundstage are a big improvement over the HA-1.

I`ve started reading about tube rolling, my main concern is with the durability of the tubes that came with the amp. I will listen on the WA22 for maybe less than 20 hours per week. After how long am I expected to exchange tubes? What would be your advice on keeping a stock for the years to come? What sellers/stores do you recommend? I live in Brazil, so I guess importing will be the only option.

Best regards,
Paulo Mario

At 20 hours per week that is 1040 hours per year.

With fresh NOS tubes you should get 4-5 years (5000 hours).

You will slow down. I was doing 20 hours per week at first. Now I'm doing about 2 hours per week.

Hi all,

Here's what I've ordered for my WA22:

Cossor 53KU Fat Bottle
2x Mullard ECC33
2x Chatham 5998 (JAN-CAHG-5998)
4x RCA 6BL7GTA

The reason I bought quad 6BL7 was to use 2 per channel, but unfortunately the ebay seller for the needed adapters doesn't ship to Brazil. Any chance I can get them elsewhere?

I'm really excited with the upgrade!

About as good as it gets. Enjoy.

PS - I had a great time in Rio (and a 5 day trip in the Amazon) a few years ago.

Hi all,

Has anyone tried the Sylvania 6SN7W black base, short glass on the WA22? I got a used pair, supposedly from the 1940`s, they`re on their way.

Another question: as a rule of thumb, the more recently manufactured the tube, the worst it sounds, correct? Does this rule apply to the 5998`s? I`ve got a spair pair of Western Electric 421A`s, but the date code tells me they`re from 1970, and I`m afraid I`ve made a bad deal. Bought them as spares, anyway.

1) If those Sylvania 6SN7W are in decent condition (i.e. NOS or gently used) then they should be fine.

2) Normally, this is the case, but I have WE 421A's from 1985 (from Brent Jesse) and they sound great.

the usaf 596 tube is a fantastic rectifier for WA22! get one for yourself!


I agree it's well worth a try one of my favorite rectifiers, Black sure looks nice on the Woo..enjoy

I bought the one Jack Woo brought to the LI Head-Fi meet a few months back. But my WA22 has been at a different adress from where I've been living since then, and I have not listened with it! Seeing this, I'm eager to get it setup over this weekend, as we'll be reunited. Haha.

Yes, this is ironic as I bought it yet am asking this ... So what would you say it does? More and faster attack? More 3D/holography? More bigger heft to the sound?

Hello guys,

Can the ECC31 be used on the WA22 without an adapter? Woo Audio`s tube compatibility chart doesn't mention the need for an adapter, and Michael from Woo didn't say anything about it when he replied to my email, but the pinout from the ECC31 and the 6SN7 are different.
