Potentiometer and Fader Cleaning Pots (potentiometers)and faders often become so scratchy and intermittant that they can render a piece of equipment unusable. This is usually caused by either or both dirt and wear.
Pots are made in both sealed and open types. The sealed types are usually well made and rarely get dirty but they can become scratchy from wear. They have to be opened to clean. Open type pots are easier to clean but are often of lower quality so they wear faster.
The Holy Grail of audio pots and faders is the conductive plastic and cermet elements. When pots are made of either of these two ele..
Recapping – Electrolytic Capacitor ReplacementVirtually all audio gear uses electrolytic caps in the signal path and virtually all electrolytic capacitors need replacing sooner or later. If your audio equipment is 7 to 10 years old it may need caps replaced. If your gear is more than 10 years old it's almost a for sure.
The nasty aspect of electrolytic cap failure is that it happens very gradually at first. For instance, sonic degradation may be occurring gradually from year 7 to year 12, so gradually that if you use the gear regularly your ears will adapt and it's likely that you won't notice the losses (un..
Pro Audio Switch CleaningAs audio equipment ages all contact surfaces, that is switches and connectors, become oxidized and can develop a minutely thin coating of plain old dirt (airborne contaminates like tobacco smoke, other kinds of smoke, soot, smog and super-fine dust). This condition can render a piece of equipment intermittent of unusable. This can be very aggravating, especially if the unit is otherwise valuable or just valuable to you.
There are many sprays on the market that claim to clean up dirty and oxidized switch contacts. Some of these work on very lightly oxidized and dirty contacts, but they are usel..
