    Hi all

    After a gap of approx two years I am finally getting back to messing about with audio kit.

    This thread is for my version of the A&R A60 power amp that also contains the Velleman
    speaker protection PCB - detailed in this thread.

    https://pinkfishmedia.net/forum/threads/kicad-velleman-k4700-dc-offset-detection-pcb-updated.246070/

    The picture below is how far I have got - nearly ready to connect up the mains/control/PSU/etc wiring - and then the
    big question.

    Will the A60 PCB work properly - completely untested as of this moment.

    This is the 3D image of what KiCAD thinks it will look like when it is completed.
