Is this a 2-prong AC plug? If so, try reversing the line cord AC plug. If not, there may be some other offending component. What happens when the Pre is plugged in & turned on without any inputs or output connected? If the chassis is still hot then there may be a failed internal bypass capacitor.
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
