Aleph J problema for adjust Offset and Bias

[Morenmgu]

Hello, I'Miguel from Spain, I think this is the place for technical question.

I'm building a Aleph J amplifier board and now it's time to adjust Offset and Bias. I fixed the bias resistor to 68k and swich on the amp.. then i check the volts of the exit post and see is 23.5 volts, and when I turn the Offset variable resistor, the value not change, are fixed, bouth pcb's has the same problem. Do you some experiencia with this problem ?? I check all a lot of times..... In the other hand, i see when check the exit, the positive out of the righ chanel is in the gnd exit....

Adding that the Q1A and Q1B are hot.

Thanks a lot in advance for give some light !!

I'm sure is somethink stupid from my side.

Thanks
