OK. Looks like "R6" has multiple diffusions, the green appears
to be N+ and maybe they "replaced" 150-ohm Pbase R6 with
a lower valued N+ "bridge" to let them not-change Pbase and
Metal (needing the space to run that cross-through trace, so
can't go much shorter on contact-contact). So the resistor may
really be N+ in parallel with the remaining Pbase that's not
"stepped on", and a pinched Pbase that probably can be
ignored underneath that "add-on" N+ plug.
I'd guess that the net resistance is now something like 10-15
ohms, a slightly oversquare N+ (usually about 10 ohms/sq)
with maybe 200 ohms Pbase in parallel.
They probably left the marketing schematic as-original, just
to mess with anyone looking to copy.
Output stages and their short circuit protection seem to be
one place where different vendors of "standard" parts seem
to be prone to diverge in topology & values. Been looking at
some op amps where no two "old time vendors" agreed on
the network, component types or values. And agreement in
published datasheet schematics? Forget it, fiction galore.
