I just read through the manually and see how they are setup if you want to build external off/on switch as well as extending the leds. A little soldering possibly, but nothing to crazy. Man if this works out Steve and your happy with the performance and sound of D technology, I may have to consider this some day. Thanks for bringing this to our attention. Sure beats the heck out of the cost of other mfg'd amps with the same power. Are you going to build a mono version for the VP180 if all works out?
