Hi all and thank you for the add.
I’m having trouble with setting the mid point voltage on the output caps.
I can’t seem to get the voltage any lower than 10v below the rail voltage of 67v.
One board is fine showing 33.5v the other is 57v.
Any help would be greatly appreciated.
Thanks in advance.

Check R130, 150K, for value (drifts high), and C100, 680nF, for DC leakage., especially if it is electrolytic: change to film.
