Procedure for sorting power transistor ?

[Miles Teg]

I see around here, that he exists some things to do for sort our transistor. I know we can do it with simple alim/power resist schem. Can you remember it to me ?

are you refering to matching MOSFETS?

Look at the procedure given in the A75 article
in the DIY section of http://www.passlabs.com for matching
power Mosfets.
