There is a little Interference Noise from the volume control on this unit; only when it is being turned around, and in a certain position this happens, I have tried once giving it a good spray of Kontakt Chemie: Kontakt 60 and a few days later a good spray of Kontakt WL and turning the knob after each spray to move the spray around inside. ... sp=sharing

I have uploaded a two old photos showing the rear of this control although one of them is the balance control; there is access for spraying on the side and maybe from the centre of the end and info on Kontakt Chemie.

Can you kindly advice on this; I don’t want to do anything more without further sound advice because it could also destroy the potentiometer depending on the materials in the potentiometer :think:

Ultrasonic cleaning in IPA drying and using contact grease or Brunox will be the final solution for this potentiometer problem.
