No reply from Gustav so far

Is the "non-plus" version just missing the +48v portion of the circuit? If so, I have built that and can help. I have ordered the Vari+ psu boards from Gustav a couple times and once he sent me one that was clearly a different board and was missing the +48v, and I used it successfully in an active EQ.
