I need some advice on how to clean inside a vinatge Yamaha CR 2040 receiver that I bought some months ago and am just now getting around to cleaning. The receiver has a scratchy sound when turning volume knob, balance knob etc.
I was advised to use deoxit to clean inside.
However, when I went to a local Radio Shack, the rep told me to use compressed air first.
Is that correct?
Should I spray compressed air in the unit?
If so, where do I spray the compressed air?
Is it ok to spray the compressed air over all of the inside of unit?
Also, when using deoxit, do I just spray it on inside of knobs?
Radio Shack did not have deoxit but the rep told me the Radio Shack lubricant was the same as deoxit.
Is that true?
Thanks. I appreciate it.
