I see that Syntaur offers replacement sliders for all the AX-60 “value” inputs (https://www.syntaur.com/Items.php?Item=2187) and the upper/lower split mix (https://www.syntaur.com/Items.php?Item=7137), but not for the main volume (which is stereo/dual-gang).
Can the AX-60 main volume slider replacement be made available? Or, could you at least supply the part info/reference? (Seeing as there are apparently sources for the new equivalents for the value and split slider parts.)
I have the AX-60 service manual, but I have not had any luck Googling the part number listed there for the main volume slider.
