    Top tip if anyone wins it.

    Take the tranny tops off and get them re-chromed. I had some done by a workshop that does stuff for motorcycles. They came out superbly and cost very little. Years ago now but still a valid course if action.

    I was warned NOT to do this! Apparently the whole amp has to come apart to refit them...

    I've got another one in pieces on the bench so I can let you know whether that's true or not. I suspect it's easy enough. Unlike Richie's, this one's had some serious meddling with electrolytic caps wired back to front, film caps placed in wrong place, and incorrect resistors fitted. Amazingly it still worked and sounded pretty good but hummed!

    Obviously bought for the cage, not the amp.

    They're not a bad amp, but the power output is too high, these burn through output power valves. In an A B comparison the earlier versions Audio Innovations Series 500 (3 output tap version) to my ears sound better, though the Unisis looks nicer.

    Back in the early 90s I worked in a store where we sold both brands, and I owned a Unisis for awhile, I still have my Series 500.

    Oh my god! There's nothing wrong with the bidet is there?

    “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!”

    So this is a dead sales thread, therefore I broke no rule.
