I am currently finishing up my ACA build, kit purchased from the diyaudio store. I am planning on building an Aleph J as my next project and have decided to start collecting parts. The input jfets are back in stock so I thought I would acquire these now, however there are grades "A" through "D" listed and I'm not sure which to select. I did do a search of threads to see if this has been answered before but could not find anything.
Thanks

Depending on how much of a hurry you’re in you could wait for the matched pair they sell in the DIY Store to come back in stock.

of course - I'm encouraging if you have any other , closer , faster solution
it's always sweetest if you make your own from scratch and - when you need semis for matching - whatever is left of quantity you bought- you can always use for further projects
I didn't chime in to advertise B. J , but to tell that there are some simpler solutions , no need to blindly follow

ZM, no worries, I hadn't come across the Babelfish before you mentioned it. I am just looking for a good sounding amp with just a little more power than the ACA. I'm getting kinda old, 66, 
so my hearing is not good enough to get the full benefit of some of the really high quality amps that are being produced here. I would like to build the Nutube pre next so I am just patiently awaiting the Pass pcb.
Thanks for your advice

of course that you can buy Babelfish J package from me , if that suits you and that is probably easiest way of all , for making any of J iterations
However , as always , point is that fun is in learning what can be changed and for what reasons , and still being on target
read here : About possible Babelfish J interest
plenty of details , if I remember correctly ..... so - if you grasp at least half of them , it'll lead you to more fun - understanding more and being able to ask right questions, to increase both fun and knowledge
Papa did show us long ago that Aleph is an Aleph is an Aleph - what's important - it's concept , and you can stretch it for your own needs
