Bias Adjustment


One of my two Burmester 911MK3s is experiencing a temperature differential. After consulting with Burmester, it was determined that the bias adjustment is necessary.

Does anyone have a recommendation for a professional in Southern California who can perform this adjustment?

If you’re near San Diego, Peter @PBN Audio might take a look. Every once in a while, he'll work on other’s equipment. Very knowledgeable & cordial.

They are authorized for many brands, and even if not, have resources to work on just about anything 

You can definitely fix the amp yourself instead of spening hundreds of dollars and so much time. Locate the trimpot or trimmer potentiometer which is an adjustable resistor to set the bias current. You need the amps schematic diagram somewhere or from the manufacturer to locate it and follow the video tutorials on YouTube. It's so easy every power amp owner needs to know
