A bit of googling ... and these have been used to make 5.1 amplifiers

    Here are the (few) components:


    And the (hefty) torroidal transformer:

      Seeing as we're bringing amp threads back from the dead today...
      Any updates here Wizard?

        Matt Allison agreed to "assemble" this for me.
        "assemble" in quotes - Matt says it took him 12 hours to do.
        Not just a quick plug and play.

        I am blown away.
        Never thought I would own an amplifier that sounded like this.

        It's now replaced my very old NAD 3225 PE hifi amplifier.

        CD player --> Gainclone amplifier.

        Volume control only.
        No preamp.
        No tonestack.
        No balance controls.

        Matt - you're a hero!




          Spot the hefty transformer. ?
            Thanks for the update Wiz.
            Looks great ?

            Any plans for a pre-amp or are you enjoying keeping it nice and simple.
              Won't be using a preamp. Line output from CD player or iPod is high enough. Besides. This sounds so good I don't want to mess with it

                  Missed this thread, it's a great sound amp, building one for myself, blown away by the depth and imaging, even with sub par speakers. This took a while to put together because it's largely off board and I had to locate a bunch of parts that were not included, drill a chassis etc.

                  The PCB/kit I ordered for myself is a single board with power and the amp chips on one board, I'm tweaking the components and will share it all once I've put it together.

                  Got the custom wound torrid last week, not waiting on the kit and enclosure.

                  Cheers

                    Wizard, where did you get this tranny from? And if you don't mind me asking, how much did it cost?

                    Thanks
                      I had a look at those for another build. 35v is too high. 20v will work but may be a little low
                        I think I will try a 20v. The reality is that 99% of the time we run our hifi at 20% volume
                          Thanks Skylark. Bought two toroidals from Dexter this evening
