Update: July 23, 2004. I finished designing the output driver stage. I'll be converting this 6-to-1 mixer into 6 individual out preamps. I'm using NE5534 opamps for the gain stage, set to a gain of 20.
And the PCB design.
Next step.... building the PC board and etching it.
I designed the PCB layout using Eagle software, exported the graphics image to Photoshop, then imported it to Illustrator. From Illustrator, I did some last minute touch-ups and print it to the blue "Press and Peel" sheet.
On the right, you'll see the cleaned PCB and on the left the PCB design ready for transfer to the copper board.
PCB design cut and taped to the PC Board. Ready for ironing!
