[QUOTE="Art Welter, post: 88529, member: 52"] Re: PSA: Blow it out yer amps! Although I have heard many fans in amps "scream like a siren" when hit with 100 psi with no bearing damage, I have started to stop the fans after hearing of some fan speed control circuits that may be damaged by the voltage produced by the fans at very high speeds, as the fan acts like a generator. Also, a spinning fan blocks more air than a stopped fan, more effective compressed air (and dirt) transfer with it stopped. And TJ, if you think that a can of air is enough to remove the crud that builds up in an amp, you must be too young to remember the buildup of tar and nicotine sludge mixed with dust from smoking barroom use amps that would require a spatula to scrape off, 100 psi of compressed air would hardly do anything. The house amps at First Avenue used to be so gross that the sludge was like printer's ink with dirt mixed in, smelled like ashtrays from hell.. [/QUOTE]
