I am having an issue with the 3116 (116) I recently restored. It has been fully recapped, including all paper and electrolytic, plus three micas. All out-of-tolerance resistors changed, along with the Candohm. It plays beautifully, very good sound, selectivity great, nice tone. But...at low volume levels, there is a "clicking" noise. And, I have 64 volt AC on the chassis, measured to ground. I found this problem, after getting a small shock. And to top it off, if I connect a ground lead to the chassis, the audio develops a hiss and distortion, which stays even after I disconnect the ground. I need to shut off the set, and let it cool down, to get the audio back to normal. 

-I have eliminated the tubes as the issue; swapped all, one at a time, for known good ones. 

-Performed a dim-bulb test on the power transformer. All tubes/dial lamps removed. No glow with no load. And the voltage on the chassis is gone as well.

-"click" noise present with RF/IF sections disconnected. So, assuming it might be the audio output transformer, I checked it...no shorts detected. Even swapped an identical speaker assembly...same issues.

So...before I go and start ripping the chassis apart, or ripping out my hair, has anyone run into an issue like this? Steer me in the right direction?
