I have cats that like to crawl over everything so I can't have stuff exposed that might be dangerous. Maybe somebody has invented a wire mesh or cage to cover amps or tubes like this?

Yes, they get very hot.  If you're worried about the cats, they're pretty smart.  The Woos don't come with cages, you would just have to be careful about what's around them.

the woos don't seem to run tubes as hot as some other tube amps can, but they still get quite hot. they will definitely burn if you touch them for too long. you can probably lay your finger on them for like a split second, i used to remove some of the smaller tubes this way, touching the cooler parts of the tube, but they should be allowed to cool off or use something to touch them with to avoid burning yourself.

 

i don't think they are a fire hazard unless you did leave something flammable next to them for prolonged periods of time. its not like it will instantly ignite, but use common sense and keep papers and furniture, carpet, clothes, cats, etc away from them.

 

in particular, the power tubes seem to get the hottest

things are great with the WA5, I tried them with an HD 800 at the recent chicago meet, it was about as good as you can imagine.

No issues with cats for 30 years of valves....

Do people find the W22 worth it over the WA6-SE? Specs are similar; WA22 has balanced ins/outs but I consider that a convenience rather than a SQ factor. Other major difference (besides price, of course) is the WA22 has separate power/drive tubes whereas the WA6-SE doesn't. I don't yet pretend to understand the different roles of those two functions in a tube amp (and Google is not very helpful) but on the surface it seems like it would be a major complication in the life of tube rollers... one that would be justified only if much greater SQ can be obtained. Any thoughts?

^ if you are not going to run balanced input > WA22, go with WA6 SE.  With SE connection, the WA22 doesn't sound better than WA6-SE.  With balanced input, to my ears and IMO, the WA22 clearly beats the WA6-SE but honestly, not by a huge amount.  WA6-SE is a fine amp.

depends, I think WA22 is better when running fully balanced and with maxed out tubes, otherwise, the WA6-SE is almost as good, and perhaps better with a few headphones if the WA22 isn't maxed.

So running into a slight problem, definitely amp related but unsure if it is the amp or tubes.

 

I suddenly started getting some loud static in my left ear last night.  I switched everything off and tried various combinations, if I use the stock 6080's with the 6F8G's, I get static.  If I use the 5998's with the stock 6SN7's I get static.  If I use all stock I get no static, the recitifier doesn't seem to change anything one way or the other, I switched out between the 422, 596 and CV593, no static with stock tubes.

 

Took out all of the tubes, used some compressed air and took out all of the tube savers, put everything back in place and now no very loud static, unless I turn the volume way past listening point, but there still seems to be noise in the left ear.

 

So, me being me, what would be the root cause of this?  I tried switching the driver and power tubes to opposite sides, but always in the left ear.  Also, I noticed that with the volume up I get a hum with or without the 422 adapter in place.  At normal listening volumes, no hum.

 

I haven't tried putting the tube savers back in, currently using the 596 as well with the 6F8G's and 5998's, does not appear to be an issue but am getting some very minor noise in the left ear.  Also tried multiple headphones, single ended and XLR.

 

EDIT:  Well I give up, now it is not making humming noises or anything of the sort using the 422 adapter, or any tube combination.  Maybe I had it on for to long on Saturday?  Was on for 5-6 hours before I started noticing it.

Yeah, I've read that if one uses the RCA inputs on the WA22 only half the amp is operating since there is no "phase splitter". However I do have a DAC with balanced outputs and don't imagine ever owning one that wouldn't have such given the DAC price points I'm comfortable with.

 

Adding up costs, a fully-maxed WA22 would be $2645 versus a WA6-SE at $1366. Certainly the WA6-SE makes more logical sense given that people think the SQ difference is real but small; but dayum, the WA22 is so sexy with all those tubes. I have some thinking to do.
