>>With all the internal creativity and wonderfully unique circuitry aspects, why stop there and "punt" the chassis design? Near as I can tell, YOU should get the credit for this clone T. <<And I always give credit when one is due. So thanks again T. ,for coming up with schematic that created so much fuss on the forums, that I couldn't resist temptation to try it.
As to the chassis design, the concept behind the amp is simplicity and purity of both electrical schematic and the layout itself (at least in my amp;-)). I did consider different chassis arrangements, but nothing was as practical, cost effective and simple as those two pieces of square tubing closed together by 2 slabs of aluminum.
It makes for a very rigid construction (2 smaller elements vibrate less than one large), the size provides enough cooling, so one can avoid heatsink fins which might become a source of additional resonances, less parts altogether (so less assembly time and additional hardware). In my case the chip is mounted directly on a rear panel, between RCA jack and binding posts. This provides for a truly shortest possible signal path in the amp. To allow good heat transfer, both aluminum slabs are CNC machined with great accuracy and the tubing is tightly fitted over the 1/4" notches. There is no additional fasteners required for the chassis to be rigid and stable, but for the sake of protection, we use 4 screws on the bottom.
I am actually very proud of that design, and I don't feel uncomortable that I was copying competitior's design. The concept used to make GainCard chassis could be compared to the invention of a weel. It always existed, but nobody was aware of it, until somebody tried it for the first time. Does this mean that nobody cannot use it, beside the originator? Because, IMO, the chassis concept used in the original GainCard, is the best for the design. I would compromise my design if I would use different approach. It's simple as that and that's why I decided to go with that.
I never actually saw a real GainCard (just the pictures in magazines). I will admit, that right from the beginning I was fascinated with that small amp and I regard Mr. Kimura as pioneer of a new approach to high end, a man who started a revolution. As much as he is critisized, he is also admired and there is a tremendous amount of fresh thinking and ingenuity in everything he creates. So once again, I give credit where it's due. Thank you for the inspiration (and sorry if I upset you).
