Whats the techs behind the HI-LO switch on the WA22? Does it alter the output impedance?

Yes, I usually keep it Hi on most of my cans.

I will remove the tubes not owned from the list. Selections in Bold type.

The output transformers are tapped for two different impedances.

Nice. My Tung Sol black glass rib plate 68FG and Mullard GZ34 just got here. Even better news is that my Woo adapter for the TS BGRP shipped today! So much for Woo no longer making them or some long wait. They shipped within two business days.

 Stunning! Want to see a pix of your Tung-Sol 6F8G w/adapter.

i dunno how the WA22 compares but the WA6-SE is supposed to measure 50 ohms for high and 15 ohms for the low outputs. those where measurements done in a review somewhere i think, and i know someone on the forums emailed jack about it once and he said 60 ohms for high i think.

I have a story to tell.
 
Disclaimer: I am dumb when it comes to this kind of stuff, pardon my ignorance. 
 
So last night I accidentally unplugged my USB cable that connects my computer to my DAC. So I plug it back in, but now instead of that silky beautiful ear noise, I get this horrible feedback, buzz, hum, and distortion coming through my headphones. Naturally, I start freaking out, and assume the worst. I frantically start testing everything; I roll new tubes, but apparently one of my tubes I rolled is broken(or I suck and didn't put it in all the way), so then I think I must have really caused some serious damage, perhaps I shorted out the tube socket as well (don't even know if this is possible, but like I said, I am stupid and distraught, lol), I try multiple ICs, power cables, I try my other laptop, I try stacking my DAC on a book, and my amp on another book far from both my computer and DAC, still the same problem. At this point I feel pretty defeated, and I decide to just lean back in my chair and sulk in self-pity. As I lean back, I realize I miscalculated my lean, and that I am about to bust my ass. Quickly, I flail forward and catch myself in the nick of time, preventing insult to injury. I mutter some expletives, and I put my headphones back on, but now the noise is gone... nothing, silent, absolutely no hum, buzz, feedback, etc. I am in shock, did my clumsiness just fix my problem? I notice that my laptop screen is dimmer, and that my charger is unplugged and laying on my desk. I plug the charger back in, the horrible noise is back, I unplug it, the noise is gone. So apparently when I initially unplugged my USB cable I must have jostled my delicate cable management, and moved the USB cable too close to my charger cable. I rearranged my cables, and now everything works perfectly fine, lol. 
 
Thought I would share my stupidity with you all. Needless to say, I am very happy I just have an embarrassing story at this point.

I plugged the audio input to the sub output once. There were sound coming from the amp, but slightly distorted and the amp had some very strange behavior......

 

[keph]

need help here i just purchased a WA6SE and could anyone recommend the best tubes for using with LCD-2 Rev.1 and HiFiman HE-500 headphones..?
 
Thank you...

That's why isolation in singal cables is so important. Those little suckers are like anntenas and if not isolated properly will suck in all the interferance from electrical sources.

Additionally, make sure power cables do not run parallel to interconnects, speaker wires and other cables. If possible, have power cords "cross" the other cables.

I've recently placed an order for the black version of WA6-SE. It will be used with Grace Design m903 as a DAC and I have Denon AH-D2000 and AH-D7000. Can't wait to try this combo! Unfortunately it's 3-4 weeks lead time due to under capacity at Woo.

Congrats fellow WA6SE member. BTW, almost everyone waits that long, this is Woo's normal lead time from what I've read.

 

[Dubstep Girl]

when i ordered mine, it got shipped that very night.
 
 
only had to wait 2 days for WA2, and i could barely wait that long.
