I suspect bad interconnect are at the root of the cause...
Seriously, have you pulled the connectors apart to see if you've got a lousy / broken solder joint or something obvious in there? I assume since you're asking here they're not new ICs or you would have just returned them.
You didn't loosen up a jack or two swapping them in/out, did you?
What are your old ICs and what other stuff do you have? Tube preamp???
