I think I've exhausted my searching and testing, and I still can't get this thing past step 5 in the HTBUA6100M Manual.
The LV2000 is putting out +-25V
All transistors are tested, wires checked.
Reflowed nearly everything.
The only anomaly I can see is that D807 & D808 diode check at 0.3v. The schematics call these "Germanium Special Diode" and I'm not sure if they should be more in the range of the other diodes.
