MS20 Filter

[tomg]

Here are the scans...I'll be glad when all these boards are done and I can
just say "buy the board" instead of taking my synths apart to provide
pictures. BTW I am going to do a pcb for an improved version of this 
dual-filter soon! (within 30 days) Good Luck Keith I hope this helps.
