Ben, When I cant find a HV leak I try these two tricks. First and easiest is to run the set in total darkness to see if you can see the arcing in darkness.
If that fails I get a few feet of heavy wall 3/8" ID vinyl tubing and stick one end in my ear and probe the suspected area where the HV leak is, with the other end sort of like a stethoscope. The sound of the HV leak will get louder as the end of the tubing approaches the location of the leak.
