Hi hi hi there
I have my xbosoz nearly up and running (thanks again Kari)but is playing tricks on me now. I am getting a drop to -3.1V on the amp board and no amplification.... the psu on its own produces the correct -12v and 60v I am not cascoding and have followed Karis guidelines ... being:
If you choose not to cascode you can omit R10,R11,REF1,REF2,Q2,Q3. You also need to short Q2,Q3 D and S.
I have thus shorted the d and s of each q2 and q3 . I have tested both boards I have and both have the same problem. The + side drops slightly but is around +60.
Anyone help ?
