I hadn't given that any thought, I suppose either way has some advantage. They all are within the original specified range so either way will work. I'm planning on installing mine with the tighter matching per channel with respect to the input/output of each triode.

All Overseas shipped TODAY!! Sorry for the delay, my day job has been devouring all my time the last few days.
For now no sets left. However, I kept two for myself but I may not use one of them. I bought a board with the fairchild Jfets from the diyaudio store and I plan to do a side by side build of it vs the Algar emi board. They both have tentative homes, which could change, I'm saving a set of the Toshibas in case the quality difference is noticeable. Would you like me to let you know if I'm not going to use them? It maybe a while.

Some will be going into future ACA builds, socketed to allow reuse in other projects. Maybe another B1 (Korg). Maybe extra buffers for balanced preamp outputs.
I'm also trying to remember where I may have seen an N-type JFet differential input stage for something like the Aleph J.

That's correct, the normal ACA wouldn't need matched JFets.
I'm not building normal ACAs.
