I have an old venerable CP 50, which lost its both knobs due to the aging of the plastic. Is there any way to get the replacement other than from Moto? Online vendors are flooded with cheap Chinese GP340 knobs, but I am not sure if they can fit the confined top of the CP50.
The axis of potentiometers in CP50 is of ca 3.5 mm in diameter, while one axis is also fitted with a metal piece, which widens the diameter to ca 4.1 mm. Both axis are spaced ca 15 mm apart, and the original knobs were tiny. I think that the CP50 channel knob resembled the volume knob from the GP110, while the volume know was tiny. Any suggestions are welcome.
