What you are describing is likely an excessive leakage path from the mains to the chassis. I would discontinue use of the product until it can be evaluated and serviced. It is very possible that the leakage can accelerate to a level that can cause a hazard to someone that may come in contact with it. There is also a chance of a fire resulting if the conduction path is via a flammable component. This is not something to ignore. Kevin Halverson
Help!! My tube pre amp is shocking me!!
I just hooked up my Anthem Pre 2L and it pops and shocks me every time I touch it. Also, it pops in such a way that it makes a loud POP sound through the speakers and temporarily lowers the volume and slowley comes back to full strength. I have no idea why it's doing that and if someone knows why please let me know. thanks
