Well after 5 years of good service it seems as if my Sherwood Newcastle AVP-9080 is starting to act up.
While watching movies I have noticed a very distinct buzz, almost like a ground humm, coming from my system and it is only in the subwoofer channel. After following the tips for elimination of ground hum and connecting and disconnecting components I have discovered that the Humm/Buzz is coming from my preamp.
I have disconnected the sub and swapped connections to the main amps and the sub channel and the buzz continues but only in the sub output chan. The other channels are dead quiet. Also the buzz only starts when there is an active sub signal.
Well If anyone has any suggestions on what I can do to fix the problem or if anyone knows what the problem may be, please let me know.
Obviously the warranty has expired and I am not looking to spend a large amount of cash on repair.
Thanks in advance for any help.
