No, I don't think it is a typo. The review even mentions that the prototype has 10 tubes but the final will have 11. Jack Wu told me recently that they had achieved a breakthrough of sorts in their last prototype that made the amp better. This version of the prototype is supposed to be headed my way soon for the Aug. 8 NorCal meet.

You're right Al, I just read the review. Jack told me that the final production version will truly blow away the prototype that was in CanJam.

Woah! Impressions as soon as possible please ;D

Hahahaha you replied faster than I managed to edit my silly question :palm: Saw the price in the Woo website :rolleyes: Thanks Al.

Hmmm they've added a sole 12AU7....

Why, I wonder.

Maybe it's used to invert the signal for single ended inputs?

It's probably a phase splitter for the SE input. We'll see when they post the internal pics... :)

You mean by JP#s carrying it up North or some such?

Yup, that's the plan. Not sure exactly when the pick-up will happen though, could be this weekend...

Yum yum, that sounds like a very interesting meet. I kind of hate you, but just a little bit ;D

That's what Jack said at CanJam to me - the final version would have double the voltage swing and 30% moar power.

I'm still QUITE disappointed that we wont have the KGBHSE at the July 25th Colorado meet. Is there any chance that it will be back in Colorado in time to compare to the A-10 before I send the it back? It will be a major big missed opportunity if we can't get the two of them together at the same time.

That's what it is according to their product description page

WES Electrostatic Headphone Amplifier

But 6SL7's as drivers? I really don't get that one. :confused:

why do I doubt that this is really the case? :)

The WES prototype at CanJam had a 400v P-P voltage swing and Jack told me the final version would do 800v P-P.

cool beans! I didn't realize the original design was so low :)

I wasn't sure if it was an issue with the original design, or just a bug that he didn't get worked out in time before CanJam. I didn't ask that one.
