Here's a nice working Texas Star dx667v. It has a blue led fan mounted on bottom and wired to the power switch inside amp and it has a nice plug in back to stop power to fan. I did notice a couple times when turn on power to amp the amp powers up but not the fan just wiggle switch with fingertip to get it to power it up. How I got it been good just did happen. Otherwise it works 100% Also has homemade leg set to keep it in air for fan. $285 shipped.
