Jerry,
Good job on your AD831 mixer board.
As always I like your construction style.
Are you using a single sided copper pcb?
Can you show us a picture of the back of the board?

Thanks...
Al, N8WQ

The board is screwed down on my bread-board, but here's what the back-side looks like.
yes, it's double sided board

Currently using photo resist film.  Print this on a transparency and expose in bright sun.
