Check to see if any or all of the pass transistors are shorted.

Bzzzt, wrong, would you like to try for what is behind Door #3?

If the Pass Transistors were shorted, you would see the voltage of the
filter capacitors and rectifiers on the output. He stated that he had
"No or little output voltage". This would indicate that the Pass
Transistors are OPEN, blown that way by the High Current when the output
was shorted, or the rectifiers are blown OPEN and not producing any
DC to the filter caps.
