Question about Amplifiers & Preamps
Hi I think the volume pot on my amp is faulty (lots of crackle when I turn it up or down, but not always in the same spot on the pot or all the time, prehaps it's something else??)
Where can I get a spare one?
Steve I have a NAD 3020and the carbon granule volume POT has a couple of noisy/dead spots. Where can I get a replacement Thanks Geoff
Rotating the pot a couple hundred times MIGHT work but might also grind in the debris on the pot.
The best thing is to unplug the unit,take the cover off , locate the pot and see if there's enough open space on the pot itself to spray contact cleaned into it.
I recommend any of the De-Oxit brand contact cleaner.( Not a paid consultant)
Radio shack even carries it.
Flush the pot with a couple sprays of De-oxit and rotate a couple dozen times

Hi....sounds like dirt or pitting on the carbon tracks in the pot.
The cheap solution is to USE it....often the carbon /graphite tracks will re-whet when rubbed by the wiper in the pot and hey it's ok until next year ....BUT............I mean do this....
Turn off the power and rotate the volume knob appx 100-200 times back and forth...........power up and check.
Use low continuous frequencies (synth music?) if possible as the lower the frequency is, the nearer it is to dc. and really exposes these faults easily.
Or spray WD40 (fix all graphite spray) into the pot while rotating.
OR get a genuine spare....off the..net I guess
OR get an equivalent from your LHS BTw............it is a good amp..........had one myself.......IT shook the Hi-Fi world by its' simplicity price and zero BS""t..........I knew the designer thru Dolby London where i was working ..top man.
