I have a distinct subwoofer hum when I crank my Samson 700 to max. This is caused by the cable TV coax.. verified by pulling the cable to the TV from the CATV surge protector and the hum goes away.
I did a search here and found info that referenced using a couple of Radio Shack 75 to 300 ohm antenna transformers. Further on in this reference was a msg by a Continental Cable tech who suggested the use of an inline attenuator 6 dB or less.
At RadioShack I found a 75 ohm TV/VCR signal overload attenuator (6 dB attenuation) (part no. 15-1257a) and tried it.. but it didn't work. Is this the same thing as the tech referenced?
I guess I'll return the attenuator to RS and try the antenna transformers unless someone has a better idea.
Any thoughts?
