Add an 8 - 25 ohm (depending on the volume level of talkback you want) across the speaker jack to chassis ground. This will give you talkback. You can use a pot as well to turn it up or down , use a 100 ohm pot from the shack...

Easy way to do it doeboy is to jump the ext. speaker jack to the pa jack with a 100 ohm resistor. It gives you a clean talkbck with little chance of you making it squeal. If you want an adjustable talkback do it like 307 says.
Hope this helps.

use any from 100k to 200k,100k will be louder than the 200k ohm or use a variable resistor
