Hi for sale is my Black Gen 2, Woo Audio WA22 with NOS Amplitrex Tested VT231 Ken Rad Black Glass, and Woo Audio Paired Tung Sol 5998. Rectifier is stock. I was using a 422A, but dropped it during cleaning =(. I have additional 422A I collect that I can supply should you need one, but the price will be market price. I have other items for sale such as a new or used Sony Z1R that would pair well with this if you are interested.

The amp is in 9.5 physical and 10/10 working condition. I give it .5 off because it has very minor nicks on the front bezel that would go away with a perm marker or touchup.

The amp has never been modified.

The VT231 are cosmetically near perfect (Currently $300-400 on ebay) and measure:
7.6V / 2.5 ma/V
7.8V/ 2.4 ma/V

The 5998 are not same label, but sold to me as paired by WOO (currently $999 on WOO) and measure as:
9.8 / 16.00V
10.7/15.38V

On my AT1000 auto bias.

I actually own 8 pairs of 5998 and 10 pairs of VT 231 black glass. With these above installed, the WA22 Gen 2 I have has near 0 floor noise with my focal utopia, which was important to me.

I think that there is not a better small footprint tube amp on the market today. You are getting a discount on the OEM and MSRP pricing but, more importantly will save time on true balanced , near silent tubes which to me, is priceless.

I am only selling to clear space. I have 2 other amps (Envy / Custom DNA) I am using right now.

Market Price new : 2699 + 450 + 999 = $4148 + tax without knowing if tubes are balanced / silent

Local Pickup only @ 90025, cash, no shipping. If this does not sell, I'll keep it for nostalgia. No trades. If you bring a portable DAC and analog cables you can test but I have sold other items on headfi and have ebay ( 728 / 20 years 100% ) and have professional audio references, if you are looking for feedback.
