Personally, I wouldn’t use WD40 to clean the volume control. I would use an electrical contact cleaner. WD40 is good for rusty bolts and things of that nature. When I worked in a Hi Fi and TV store in the 70’s and 80’s, One of our new techs, fresh out of school, used WD40 to clean a TV Tuner because it was very staticy between the stations(the old mechanical type). The tuner was toast after that because it left a film on the parts and wouldn’t make good electrical contact.
NAD 7175 PE vs. Newer Integrated Amps
I have a NAD 7175PE rated at 75 watts/channel but delivering at least twice as much power as that conservative rating. It has just about every feature and dexterity one could imagine, but it is over 30 years old, and needs some refurbishing...mainly the volume control... that occasionally needs to be twisted clockwise and counter-clockwise to engage the signal without distorting.
My question is whether to spend a few hundred dollars getting it back in shape, or purchasing something new...like a Marantz PM 6006 or a Cambridge CXA 80. Is there any technical reason these newer amps sound better than the old NAD?
Opinions appreciated!
