Wayne,
Let me know when you have values nailed down for the Pi-TAX beta testing...I can implement them when I put the boards from Gary together. I'll be chasing parts for a couple of weeks still. Once the boards are "in hand" I can see about the needed tube sockets, and consider my chassis options...might even be able to unearth a pair of 6DJ8 NOS tubes:) Are you staying with that tube?
Not knowing the final values makes it a premature question...BUT WHERE is a source for the close tolerance caps in pF sizes? Sam

Will do. I think Kevin Grier is planning to do the same. Should be right around the corner - I'll keep you posted.

I have the parts purchased for a 650 hz x-over (for my altec 416 pi's) and a chassis laser cut and powder coated that I will pick up this weekend. I also have a pair of gary kaufman's boards for steve bench's circuit w/o any compensation. when I told wayne what I was up to, he got interested in refining the circuit which he is now doing. I am going to try mine with and without compensation i think. I'd hope to have it built by the new year, but then I'd have to build the speakers too cause all my other speaks are FR single drivers.

Kevin
