VMPS RM-40 Damaged potentiometer?

[marcomariutto]

Hello, I am the lucky owenr of a couple of VMPS RM40.

The speakers have two potentiometers each to set the attenuation of the mid and highs.

I noticed that the potentiometers for the mid-range attenuation make a sketchy noise while rotating them, and also in some positions the mid-range totally disappears (almost like the signal is being completely cut off).

Is anyone familiar with these potentiometers on the RM-40's?

Do you think they are somehow fixable or the only option to fix the problem is replacing them?

Thanks in advance for any suggestions 🙂🙂

Have you tried DeOxit FaderLube F5?

Thank you for the suggestion, I am I'll try it.. the painful part is that in order to access the potentiometers have to uninstall the lower woofer and the crossover board. ��

Get the Lpads/pots out and measure their resistance.
