YAY!
It's finished
It sounds quite amazing.
Very smooth and detailed. I ran it in with some old speakers I made but it has graduated to my proper speakers now, I can't stop listening to it, it keeps making me grin because it sounds so good.
I know this won't be very interesting to everyone because it's very basic stuff but I'm chuffed to bits.
I have used 2 dual mono kits and a shielded 500VA transformer, it's in a 2U 19" rackmount case which while not a pretty thing, works fine and it wasn't too tricky to assemble because there is loads of space.
I have shielded all the mains power cables with knitted copper wire tubing, I don't know if it helps cut down on EMF but is certainly won't hurt. I used socket 7 processor heatsinks because I had loads spare for old types of processors at work which I'll never need to use.
So far I have only grounded the CHG from the boards so there is a very slight hum if I put my head right next to the woofer. I'm reading up on grounding now.
This is very useful actually Linky
I have started building the capacitor and snubber section of the snubberised PSU from the Db dungeon site - one of CarlosFM's designs. 1 board is done, 3 more to go. I'll pop them between the power and amp boards and see what sort of difference they make.
I'm dedicating the amp to the 6 diodes and 1 capacitor which paid the ultimate price in the construction because I mixed up the + ground and - ground wires.
Thanks for your help in answering my questions in the other threads, much appreciated.
Here is a pic I took on my phone when I had done the first 2 channels.
