Missing rail at the outputs, what would some possible solutions be. This is the older bd model. It came in with a burnt power supply and driver card. Repaired all of that now missing rail voltage at the outputs.
The regulators are all Correct. The capacitors are all brand new as well.

That's the rail voltage.
Do you have that across the rail switching transistors (the drain and source that are NOT connected to ground)?
Do you see oscillation on any of the driver ICs?

Lm317t was bad had all negative voltage, once I repaired that I have a normal +- rail at rectifiers. It had some bad trace holes, had to clean them, out with a resistor to make contact again. Once I had that repaired the +-33v could get to the output section transistors.
