re: no 28

Today is a sad day! I managed, during moving, to snap off the potentiometer of my No.28. (Monitor Select knob) I have the knob, but needs to replace the potentiometer. I would be very greateful if anyone could help me locating an replacement potentiometer?

I am not sure if you will be able to obtain parts from a dealer in Norway, but send an email to Harman International and see what they recommend. They might be able to send the part. My experience with ML products is that a lot of their parts are non-standard and you won't be able to find a generic replacement. Also due to the value of the product you would probably want to use the correct part to maintain the value.

Their email address is:



re: no 28

well, you might start by identifying the monitor select as a switch and since you have the unobtanium knob which is the valuable part....go to a tech and get a replacement switch...
