Typically, you want it behind the power tubes and blowing out the back of the amp but I think almost anywhere is good if you're using a combo amp. The issue is that most fender style amps trap the hot air because heat rises and the back panel tends to encourage the hot air to just sit which basically just applies a "kenner-easy-bake-oven" principal to the components in your amplifier!Originally posted by 8nthatK
Where would be the best place to wire the fan in? I've thought about adding one myself...
Actually, because of the fan, the chassis doesn't get hot. Warm yes, but not hot. Silicon caulk, the good stuff, is rated to fairly high temperatures. It also acts as a cushion for the vibration of the fan.Originally posted by jzucker
I wouldn't trust that hanging upside down on a hot chassis in a combo amp!
If you have a link to any sites with brackets for the fans, I'd appreciate it. Regarding the circuit, it's pretty simple. Use a 1V 50A bridge across the 6.3v taps and filter the output with a 2200UF cap. You'll get ~9v of power.Originally posted by KLB

Some of the DC box fans already have mounting brackets.
When you get this figured out, please e-mail me a schematic of the circuit you used!
I'm going to put one in my Deluxe Reverb.
PS - The Jensen appears to be sold.
The rectifier and cap will smooth the ripple and convert the 6.3AC into DC and since it's a DC fan, there shouldn't be any noise induced by the fan motor.Originally posted by 8nthatK
Hmmm...O.K. I guess I was overly worried about possible hum or other noises caused by the fan. I wasn't sure if you were isolating the circuit in any way for any reason
