OK, Gunslingers, now you’re going to know I like to do things low-cost and half crazy, but I have one for you to try …

So, you want improved circulation AND silence for an amp that’s mostly ‘in a box?’ Don’t just create slits for entry and exhaust air … put a ‘chimney’ or two on the exit air flow.

Let’s say that the amp is in the lowest part of the cabinetry, sealed off from the rest of the gear, and that there are 3 or 4 feet of cabinetry above that. Create a thin-walled rectangle-shaped tube that runs up the back or sides of the cabinet for 3 or 4 feet through which air exits from the top of the section where the amp resides. Or use readily available pipe of a few inches in diameter, depending on your taste/style. Be sure the total cross section is 24 to 36 inches … as in one chimney 12 inches wide and 2 or 3 inches deep, or two pipes that are 4 to 6 inches in diameter.

This set up seems to do little at first. But once the air begins to warm, a slight updraft will be created which will encourage a greater air exchange than just a couple of ‘holes.’

Now, of course, a more ‘open air’ installation would be the easiest.

And if you going to use fans, I will post a suggestion later for an installation technique used in some professional installations.

Well, go ahead, lampoon the chimney idea!
