This is a classic case of fault finding 101 Rob and should take about five minutes to resolve. After making sure your power supply rails are there and in spec, stick your signal out of your sig gen into the IP socket, then follow the signal path with a scope probe. so, into the IP socket,have you got a signal out of it? Is there a signal at the volume gain pot? Then onto Q1 or IC1 or whatever. Where the signals disappears or is low, check voltages, pull and test components.
After mucking about with amps for 10 years you should have this down pat by now mate, it's very basic stuff. Don't wish to be harsh but if this sort of thing isn't familiar to you maybe some reading up or even better putting in some bench time might be beneficial. Do you keep notes of your work? Definitely worth doing so you can look back and get some pointers if and when you find yourself in a similar situation..
Good luck, Andy.
