Seems wise to check the 10volt spec as explained in the original article...

Adjusted the drain of Q1 to 10 Volts.
My little red ACA chassis from the DIYAudio store can handle this extra heat very easily.

The scheme reports 2K21: the resistor should be 2K21 (1%) or is it the same using 2K2, normal 5% tol.?
