2006 Lonestar -- fan running causes a buzz in the speakers

Post by faustmill » Fri Nov 03, 2017 8:16 am

After the amp warms up for about 5 minutes, the speakers start to buzz. When I turn off the fan, the speakers are silent. Will a new fan fix this or is this a weakness is some other part of the amp? 2006 Lonestar 2x12. Thanks. Phil

I'm sorry that I cannot help you and there does not seem to be much action on this forum.
If I were you I'd call Mesa customer service. They have been very helpful in the past.

Only thing which i can think off, maybe one of the preamp tubes is microphonic and picks up the magnetic field from the fan internal parts? Tap with a pencil lightly the preamp tubes to find out if a preamp tube is causing this problem.
