it's for my Aleph 5 (12) and for a Aleph X (16)
Thank you

better try it on 200mA

Since they are intended for an Aleph 5, you better match them at 1A, since thats what they will have to put up with, in real life! Just under or at 15V and 10r (at least 20 watt'er) in series will get you in the ballpark! Takes a sturdy regulated supply, though.

Actually, the output MOSFETs in an Aleph 5 are run at something closer to .5A.
...But you can run them harder if you want to...

I start again my appairage with alim 15 volts and resistor 10 R
20 Watts.
It is well that
Thank you for your answers.

hello




if bias = 2A, ==> 0.66 A/fet and R =1.8 ohm
