<font color='#000000'>I have a constant buzz in my speakers I assume is due to electrical interference (its loudness doesn't change with music volume), because it didn't exist until I moved into an older building. I've swapped out cables, speaker wire, changed the extension cord, and determined it's not the CD player or tape player. I ran the extension chord to two other outlets, one on the same wall, the other on the opposite wall, to no avail.
If anyone has any good suggestions, I'd appreciate it.
Thanks.</font>
