<div>Thanks everyone for the replies. The circuit I'm building is a version of the JH 2040 VCF. I'm using SSM2210 and SSM2220 (lead free) for the matched pairs. I usually use sockets and build or veroboard (no strips). I'm figuring, if I really screwed-up the board and I can't get it to work, I can at least salvage my chips and try again. Keeping my fingers crossed.
