    Completed, all bar the lettering which I'll sort in due course.

    I've also added a chassis earth and ganged it up with the pot switch earth to be taken back to the main amp's earth.

    Photos of (almost) completed control unit. Won't get a chance to try it out for a while so it'll sit around for a while no doubt.








    Front, minus decals/lettering (to follow):







    Rear view: IEC is there but left unconnected whilst I use this as a passive control unit.

    Very nice, tidy job Paul.

    That's a high end looking case!

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    "You don't have free will. You have the appearance of free will.”

    “There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

    The Radford is the real star in this story

    Thanks Paul for your kind comments anyway. IEC came with the case kit, so it was fitted 1) to blank the hole in the chassis and ii) as in time, it may become an active project but for now, it's intended as control unit for an STA25.

    Thanks John. The case is a nicely made thing although it needed a fair few more openings and personally, I'd have a slightly different arrangement at the rear. I selected that case pertly as it has to support the power amp which is 17 or 18Kg (still only about half the weight of the Emille!)

    Yes a nice case

    But I wouldn't be running the left and right channels together in the same cable.
    I've experienced channel corruption when I've done so.
