My Biggest Fan

When an outdoor gig is coming up I often dust off the lead sled and practice with it at low volume. To help refamiliarize myself with the amp. This may seem pointless but it does help and I like to check the amp after periods of not being used. The thing is for low level practice I switch of the fan. I never do this on stage of course. The switch is non standard as far as I can see. The amp is a Peavey Classic 400. Am I pushing my luck doing this? Things got a bit toasty yesterday nothing broken yet.....advice welcome.

I'm thinking a better check would be settings you will be using in a live environment, prior to the show...

... is the fan really loud? Like, loud enough to hear when you're playing at low volumes? I'd leave the switch alone...

Allot quieter than the minimax fan. And an option to switch it off.....a live check always takes place of course. I think there are similar amps without active cooling but it is there for a reaon. So maybe I will have to leave it on .....

Not sure where you store it, but if it's sitting that long, maybe open it up, using a compressor to clean out the cobwebs...

... at work, we've had weird problems crop up with computers, which run pretty much 24/7 (in a dusty environment)... as a preventative, we remove each one of them, open the cover, and blow the snot out of them, at least once a year...

... so the on/off switch (on the amp you have) was a mod? I could see turning it off, when the amp is not in use (between sets, possibly).

Was indeed a mod for recording by previous owner I believe I will double check.

Don't forget to check the radiator fluid.

As I understand it, amps run hotter with age due to the deterioration of components (...including heat sink compound itself) and, in turn, the heat acts as an accelerant. I see no good reason to defeat a cooling fan. If noisy, replace.

Your Classic 400 has a fan? My Classic 400 didn't have a fan in it and I bought it new. Someone must have added one to it after it left the factory.

Hence I think with this info it's ok to run without? I bought the amp apparently ok but it had issues and took allot of work to get it to run reliably. The previous owner added the switch but not the fan as I recall...I had no idea it was not standard... Thanks for the info.

They are referring to a ceiling fan.
