Crown 800 CSL

Ok here's where I'm at. I only have -1v on the -vb supply. The +vb is 44v.

With the PA disconnected I have:

-vb = -41v
+vb = +44v

What do ya'll think is the likely culprit? And is there a way to make Q10/05 work so I can test voltages around them, chunking things, without the PA connected?

So I guess we're stuck on this. Enzo, JM, JPB, and suggestions? If not please tell me I'm screwed. haha
