Looks very nice indeed, pretty small which is always a bonus for a tube amp. That "fake" transformer cover kinda has me wondering as well. $600 for a tube pre-amp ain't too shabby, that's for sure. Of course the real question is, how does it sound?
I think the transformer goes into the transformer cover so it's not fake, just a preassembly photo.
I'm betting he's right. The toroidal transformer goes in there. I wonder if this is the same design as the original WooAudio amp in a new case or if there have been any circuit changes. The one difference I noticed was the ELNA/WIMA capacitors and Dale and Vishay resistors.
Edit: Congratulations to Mr. Woo on a new product.
It sports two 6922 driver tubes. I'm using a WooAudio 1, which has only one 6922 tube. There is some noticable crosstalk because of the single tube. I expect that the WA3 have unnoticable crosstalk and lower noise floor.
edit: I can hear the crosstalk only when if I adjust the balance to one channel, or only connect one channel.
Oh, and the transformer box does indeed house a transformer.
I wonder if Mr Woo would kindly grant permission for someone on the forum to review his products. Im sure a lot of us here are interested but cautious. Kinda like a flock of sheep just in need of a push in the right direction. Maybe there is someone who is local to him?
