Cool it!

I have to house my amp in a cabinet. There is significant upper air space but limited on the sides. The back is fully open. I use a temp controlled Middle Atlantic Cab-Cool that is installed at the top of the enclosure extracting air from front to back. It is rarely on. Works great. It is nearly dead silent. Even looking at it it is difficult to tell if it on or not.

External fan or two, O2 Cool battery powered fans work great. O2 Cool. Get it?

I would ensure that the bias is correctly set first.  That would be my very first thought before fans and all that.

enjoy

bias? Please explain...
Thank you.

Many, if not most, of instruction manuals start with "do not expose to moisture/water" or some variation of thereof. Not that it should be mentioned, but apparently.......well, apparently not everyone reads instructions most have learned early in life. First grade of elementary school early.

While at that, do not use hair dryer in the bathtub.
