    At least the holes are all round I really like the latching LED switches for amp projects.

      Nice switches. I'm putting a toggle on the back. There will be two LEDS in the front panel indicating power to each channel. They supplied red and blue LEDs. I know blue is the preferred color here at PETT, but I think I'll go red.

      Looking good! I don't care for blue LEDs. I use the white LED switches and dim them as needed.

      Putting one of these together in a day at an "Amp Camp" would be a chore. The nice DIYaudio kit back panel vs my crude labels.

        I think your back panel came out really nice. Especially since that's a lot of holes!

        They do have white letter on black label for label makers which would possibly get you closer to the big company style of lettering... Brother TZ-E335 Label Maker Tape, 0.47"W, White On Black | Quill.com

        I was talking with Kevin a few years ago about possibly having some adhesive textured plastic sheets made up with various electronic logos printed up such as you would have used on your amp... like (+) and (-) Out, In, power logos, and a bunch other stuff. It wouldn't be a slick as the silk screened stuff on the pre-made up amp back, but it would be pretty good for DIY stuff. I didn't proceed with it as I just had too many things going on at the time. I was thinking of having multiple things printed on a sheet, and you would just cut out the icon you needed, peel the adhesive backing, and stick it on.

        It was an idea, anyway, didn't say it was a good one.

        Your amp is looking really nice, and it's fun watching it progress. Thanks for posting the details. I've dreamed about making my own amp for years. I have the stuff to make one, but I want to make the case myself, so it must wait until I'm thinking clearly about it.

          I could not find white on black tape to fit my cheap little Brother label maker, and I did look.

          Every hole is an opportunity to fail, thanks for your kind words. I'm sure your future amp will be as nice as your little boombox radios and speakers.

              Looks like it's almost time for that first magic moment...sans smoke of course. The positive speaker terminals are tied to ground, interesting.

              Inverting amp? Flip the output polarity! Boom, done.

                  So, in bridged use a pair of these have plenty of power for a 2.1 nearfield setup. They were crossed at 80hz and played through 8 ohm Continuums. I will set them up in the living room with the Zingers to explore full range use single and pair, later today maybe. I have a mess to clean up in my listening room from building these.

                    I love the smell of warm electronics in the morning...

                    They came out great, looks very tidy inside. Something for me to shoot for if I ever get off the bleachers.

                    I noticed the positive speaker terminals were connected to the power-in, I but I thought it was the negative side... I know nothing about amps.

                    Specifications:
                    8 watts per channel from 20 Hz, to 59 Hz and 61 Hz to 20,000 Hz;
                    2000 watts per channel at 60 Hz.

                      Excellent build guide for this amp and an update for the 1.8 version which changed the rear panel only. Oodles of much better quality photos than mine, even some videos.

                        If I were to build a practical amp, it wouldn't be this one. The kit is really nice, well supported and documented. But it's very expensive for the results. If I wanted a nice looking wooden case project, I would look at the tube amp kits from Tube Depot. They are bare kits, I think they supply a board to put it on. You could make a really nice looking desktop item. If you don't have young children present you can leave the hot tubes exposed for viewing pleasure.

                        AEIOU built a very nice looking amp from one of these.
