Default Power of Burning Amp 3?

I can't for the life of me find what the output power of the BA-3 is. Can someone provide this info? Complimentary, ideally into a 6 ohm load. Also, to make the BA-3 an integrated amp, all I need to add is a stepped attenuator, correct?

I was hoping to build these, but my speakers are a bit power hungry, and I'm not sure whether to build the BA-3 or the F5T. I want to do an integrated pre-amp/amp.

Yes, for simplicity sake, I'd just do 3-pairs per channel. And if that's the same as the BA-2, what would the output be?

On second note, it looks like the BA-3 FE boards are out of stock.

Btw, running BA3 with 32Vdc in balanced can get you almost 200W but it'll be massive amp.
Should be easy to make your own pcb as NP was so kind to publish pcb in the article.
