I just got an brand new Aragon amp, it hums. When I disconnect cable for cable TV, the hum go away. What is the problem, is there any fix for it, can be be done DIY ?. Thanks in advance for your help.
I beleive what ncarve was trying to elplane is that if you use a 75 ohm to 300ohm adapter and back again (75>300>75) it will break your ground loop and eliminate the hum.
