The TL084 chips arrive tomorrow. I'll see what transpires after the replacement of those. Starting to lean towards IC58 being the problem, but I guess it won't hurt to replace those TL084s either.....

Yes, it can hurt to replace those TL084s. Are you just randomly replacing bits one at a time and hoping you get lucky?
∗TEST∗ - then, if the part is faulty replace it. Don't just charge in and start ripping parts out hoping that this one, maybe, might just be the faulty one.
