there are many different schematics for that Bandit since it has been around longer than just about any other Peavey amp.
if you call Peavey at 1 (877) 732-8391

give them your serial number which is stamped on the back plate of the amp, unless it is worn down beyond recognition or removed,
they will send you the exact schematic for your rev,
but it is probably about the same for most amps, if worried about it, simply use the pig tail wires, usually blu and yel, and solder them to the ext output jack, i believe yel is plus, blu is minus.
do you play country? for some reason everybody in Nashville plays a Peavey Bandit, i guess it is because they are built like tanks and do not fall apart when loaded down concrete steps on a hand truck, the Fender Blues DeVille has a very tough time surviving this treatment and so keeps many a tech busy in guitar town. Bands in Nashville start playing at about 11 am and go til 4 in the morning, rotating clubs until their fingers start bleeding through the super glue.
it looks like there may be a slight change in sound as another .33 resistor is switched in via the phone plug, which will decrease feedback by 50%, the sleave of the phone jack switches in another .33 resistor to ground, so now two .33 ohm resistors in parallel which equals half the value of one .33 ohm resistor.>
if you want the exact same sound, clip out one of the .33 resistors, easy to spot, big cement sand blocks,
or just clip one of the leads in the middle which can be solder spliced later if you want to run int and ext spks together.
