Interesting Observation:
All humming of the subwoofer stops, if I connect the casing of the STB to the ground pin of a socket.
Is this safe to do? |
I would expect the external case of any appliance to be grounded, especially a metal case such as the SA STB. In fact I am pretty sure it is a requirement for small appliances to be case grounded. Sounds like a loose connection in the STB which could have safety consequences.
Before you get a tech out is the earth pin in your STB lead connected and tight?
