Sorry for the confusion on my part (a large load of repairs going at once) but what is the amp doing when the rails are connected?
If no audio, do you see the rail-rail square wave modulated by the audio when you drive a signal into the amp?

It seems to be acting correctly now. I removed the audio and now I still have drive signal on all fets. I applied the hv and now the rails are equalizing also.
