Team effort! My Son Ben & I

Well, the potentiometer checks out- I disconnected ground and got the variable 5K ohms, reconnected and it plays now- I don't have the 3 'compensating capacitors' adjusted correctly yet (is there a trick to that?), plus my workspace is very RF noisy and don't have a ground hooked up.  I need to try driving a ground rod.

Is there a way to fix the frayed speaker wires at the plug without tearing into the plug and replacing all the wire?  blob of epoxy?

   

Thanks,
Simon
