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?
You need to be a member of Cigar Box Nation to add comments!
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.
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
darryl - apologies in advance if this is a dumb question. i knew about the tape head tap but intrigued by the aux port. Can you just hook up to that on an old stereo?
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

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.

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.
