    You have no idea what you have done!

    JLCPCB in China is making 20 boards for me that I should have by the end of next week and I have a 600va 36v x 4 custom transformer on its way from Poland...

    This just peaked my interest, and yes having the protection circuit is a unusual bonus for these cheap boards. Heatsink? Oooh getting a bit thin on the ground, I might just nail it to a dustbin lid....in case it is rubbish
    Strangely, it's 'PIQUED', not peaked-just for kaizen.
    It CAN mean irritated-if you feel like it!

    I happen to have bought a chip amp based Gainclone the other week. It's great!

    PS; read the man's resume If you need credentials for the design work
    Has anyone here built one of these modulus 86 amps ? I'm quite intrigued , a good DIY'er I know from SA has been going on about this and Neurochrome LM3886 Done Right . https://www.diyaudio.com/forums/vend...0-004-thd.html

    I have built the Neurochrome 86 amps and they are extremely transparent. They are better when built fully mono with separate power supplies.

    I have bought the Neurochrome 286 amplifier and converted that to dual mono, it is my end game amp. I have also built up a 286 for a customer.
    I have also heard the Neurochrome 686, if you need lots of power that is the one.

    Highly recommended.

    Thanks for the input Alan . Have you also tried the more economic version ?

    No I've not tried that one but can guess it's not far behind the others.
