I have a couple questions; does anyone know when the boards will be ready? The store says sometime around April 1.
Second I read in one of the threads that the store Fets were being matched within their respective grades. I bought 8 LSL74's from the store (c grade ). Does this matching mean you will receive 8 matched?

Your boards are in the store now. Aleph J:

Did you receive your jfets, and were you able to get matched pairs out of your batch? Especially considering with "b" grade limits you to one set of 8.

Yes I did get the FET's and here are the IDSS values I got using a 9V battery and measuring current with a Fluke 25 dmm.
16.31 11.38 13.63 14.05 19.42 16.17 11.84 11.56
So I matched up the 11.38 and 11.56 16.17 and 16.31.
They are within 2% , that's the best I could do so I have installed them and
finished the Aleph, everything worked, set the biases and zero's. Now I am getting ready to give it a listen.
