On the off-handed chance this may help....a few years ago I found the source of a buzz in my system thru luck. The system was completely ground-floated except for the tube preamp and, at higher volumes with no source signal, it was very clear - annoying bzzzz. After trying quite a few things, I grabbed the metal rack to support myself and moved to the back of the preamp to take another look and touched the case. No, no shock! Just no buzz. It completely disappeared! I wound up taking a lead from the pre's grounding post to a connection on the rack and have been happy ever since....well, except for that tweaking stuff! Good Luck!
Did anyone manage to ``repare'' a buzz, ever?
I have a buzz in my pream. Not a hum (I can cut it off when
I use the 80hz subwoofer crossover). I tried everything known to man to fight it externally (grounds loops, line conditioners, all kind of connections, nightlights, etc.). I strongly believe now that it is an internal problem. I wonder if anyone had experience with any kind of gear with the repare of such ``buzz'' problem. Is it possible to repare and/or worth it? What can cause it internally? Thanks in advance.
