I am interested in a project of converting an old boom box to an amp. I can see how to easily wire into the volume pot on a twist knob control. How would you do it on a slider?

a little careful poking around the slider, you will likely find its solder/contact points on the back side of the board. they work just like the barrel type potentiometers we use for volume/tone knobs.
If it has a cassette player, the simple way is to tap into the tape head wires, or even easier, plug into an aux port if it has one
It only has a headphone output.
Tape heads are probably easiest to get to, but volume inputs will also work, best way to test is probably make a couple of jumper leads with alligator clips on one end and a jack socket on the other, one other thing, does it have a mic in port? that will also work, but most likely a stereo input, so you'd need a stereo to mono adapter to utilise both speakers
Mike, the aux port is usually an input unless it's marked aux out, if you have 1 you just need a jack adapter 1/4" to 1/8" or whatever size your aux input is
There is a group dedicated to radio amp conversions. Check it out at Radio Amp Group
I'll have to get to that a little later, on the way out. Thanks.
Post a couple pics of the electronics and slider in question.
