I'm cringing as I break my personal code of conduct on necroposting, but it appears to me that given the topics covered on here, nobody is particularly bothered by this.
I summon this thread back to the world of the living to add that this is also happening to our
Strand MX
console, though it only occurs from the 80-100% range on the slider, causing the GM to dip anywhere between 50-97%, generally preventing the output
level from going above 90% (confirmed using an old serial
console!)
Because of how bad the flickering can get, I'm not sure if it's truly an issue with the pot getting dirty, or if the connection is loose.
Probably a dirty pot. At the
point where it happens, try wiggling the
fader, if it jumps around its a dirty pot. Usually Slide pots have the electrical connections AND body of the
fader soldered to the board, so a loose connection outside of the
fader itself, is unlikely.
Do, not spray any cleaners into the pot. Usually the way they are constructed, the cleaner won't get into the contact area, it will just
wash away the grease that makes the
fader slide smoothly. You can clean some faders with success, but means removing it from the board and dissembling it, so you might as just replace it at that
point anyway.
If you are decent at soldering, and have a solder sucker, this can be done. Its really pretty easy, but If you have not done a lot of
PCB soldering, you may want to practice or hire a professional. Electronics repair probably bills around $100/hr, and a
fader is probably <$20, if its commonly available. If you are confident in the diagnosis of a bad
fader, and can disassemble the
console, you could just bring just the
PCB to an electronics repair shop, and have them change out the one
fader. They would probably only bill you for 15 minutes.
