Built the best I could so far with the schematic. Waiting for laterals from profusion, ordered May 1st, still havent shipped. I have a matched pair of jfets at 9ma idss. I know the damping will suffer. Should I get a set of jfets matched at 4.5-6 instead off ebay? This is a 3.2 build with FQA drivers.

Good progress gsrchrisu
For the higher jfet IDSS value the effect on lowering the damping factor is already reduced by using the FQA drivers so you might get still the same or even higher DF than the original version 3.0. You might try it anyway like that and see how it goes. EBay is quite risky anyway to get genuine parts like that…. You ate better off with sellers on this audio forum or you can get the LSK/LSJ series which have also low IDSS value.

What is the lowest IDSS that I should consider? I have seen some at 4, is that too low. The sellers on ebay that I would use are punkydawgs or Truna?(he is on these boards, from Japan) I am going to try my 9's and see how it sounds.
