I have a smallish Panasonic stereo system - model SA-PM21- about 6 years old but making fairly decent sound (for its purpose), which I want to use in my office as my NAD 3020 & JPW monitors had been begged off me, but that's another story. It has one drawback though, it has no aux input, so it can only play from its internal mp3 player, tape and radio. I like to stream music via my computer (TuneIn - especially Misterium from Spain) while working. I'm not technically inclined, so my Q : Can an aux input be added, say onto the tape input as I never use and never have used it. How would one go about or is it definitely not a DIY? Who could do that for me? (CT area)
