I'd start by taking a step back from it then. Firstly, just make sure the resistor and cap values are correct (again, another somewhat obvious statement but let's rule it out), then I'd move towards the VCF. Check the pins to see if they're working. Are you getting +/-15 V on pins 6 & 8? What does pin 10 tell you? Also - is the VCF still sealed?
