The rails are applied to the output
stage collectors like a standard emitter-follower output stage. Now the
hocus pocus begins. Each output-device has its own pair of
emitter-resistors connected to a COMMON rail on the output-board. This
rail is actually used by both channels, so appearently both channels
are in parallel. And this rail is connected to chassis ground. This
rail is also connected to one side of the speaker output jacks.

Obviously this would dump the rails directly to ground thru the output
devices and the emitter resistors right? You must have made a mistake
tracing this out, somebody rewired this incorrectly, or you are still
measuring a short across the outputs. Are you familiar with a bridged
output? That might be a bit confusing if you've never seen one before, but
there still should be no path to ground from an output.
