Evening all, Please excuse this rambling question as I'm trying to suss out how to word what it is in trying to ask... I have a 2238b which works great in all ways, no issues with sound or function. When i received and completed the initial cleaning of this unit i noticed that the bass, mid, and treble knobs were not "centered" properly. By this i mean that if you are looking at my basd knob as a clock and the 12 is supposed to be neutral, in actuality its more like 3. If i were to try and then the bass knob from 12 to 4 or 5 it will only go to 3. ( is this making sense) The same is seen with the other knobs except for selector and volume but to varying degrees. Anyone else seen this and is there an easy fix? Last time i had the faceplate of it did not seem to be an easy way to change the "balance" to reflect the true reading but I've probably overlooked something obvious. I've included a picture of my treble turned up all the way. If i try and turn it all the way down it will come back around the dial counter clockwise to the 5.
