Ok, this is how the assembled board looks like without a bracket: bb_assembled.jpg IMG_0397.JPG Measured the noise - compared to a prototype's -94dB this has around -90dB, still good, but must be better. I use an output relay with a delayed (2 sec) switch to eliminate speakers pop on power up, its …

Yup, will be interested, including bracket, for self soldering. Looks awesome! Deal, you'll get the first one! This is very awesome ~ Indeed, man :happy: Thanks! I notice your prototype uses a whole lot of IC sockets. Are you planning on supplying sockets for all the ICs on the production boards? …

I fear your accomplishment is going to be wasted on most systems it's installed in I have 5 machines with ISA slots I'm going test the card on: 386SX-33, 486DX2-50, P166MMX, P200MMX, P3-1GHz. Currently it is installed in a 22 y.o. P166MMX with original not recapped PSU which I use as a workbench …

Honestly, those former noise figures are impressive, especially as the analogue sections aren't canned. As an aside on the previous suggestions, you could also make a properly screened cable which would massively cut down on noise instead of using the stock CD-Rom one which is essentially as others …
