I've done a bunch of these and the best way to get the jacks and
switches off is to use a nipper for trimming leads on circuit boards.
Get down as close to the solder pad as you can and clip. On the pin 13
gpio I use a circuit board vice to hold the board and get a nice long
sharp needle, Place it under the lead between the ic and the pad and
touch the point where the lead is soldered to the pad with a 15 watt
soldering iron. Once it's free it's really easy to solder a piece of
wirewrap wire to it. Then I hot melt glue it in place. I feed the wire
through one of the wholes left in the circuit board left by the jack.
Now it's easy to solder to the transistor base resistor. All my add-on
parts stay in the original shell and the wire to the radio comes out the
old jack hole. see pix
