    Its cheaper to buy it ready made, so do that and save yourself a lot of bother...

    Then buy an assembled kit and a roll of solder wick.

    ...Or buy some strip board and go to Digikey.

    thx, Max.

    i run an electronics education program for teenagers, and we prefer to work with kits. No janky stripboard stuff.

    if i can't find a kit, then it would be great to find just the PCB.

    if not that, then our next option is to etch our own boards.

    We're going for lowest parts count, so i like the assembled module linked in my first post.

    Going to be a BTL, so i believe we can eliminate the series caps on the output. Don't need the mute switch. May forego the shutdown pop protection.

    My plan is to use the BTL schematic in the datasheet as-is, but welcome any suggestions.

    Are the teenagers newbies or experienced soldering technicians? If not, do you have a decent temp controlled soldering pencils for them to use? If not, I fear that you are expecting a lot for a first-timer to solder a 24-pin TSSOP smd chip.

    Let me know if you need any help. I applaud your effort.

    Think you're better starting with a simpler kit, if you cant get that chip, try Velleman kits.
