I notices the whine goes away on the dirtbag when i touch the level pot so it should be fine when i get it in the enclosure. I cant wait to get it finished. After further measuring, i have decided to go with the 125bb cause the 1590bb was just a bit too small height wise for how i plan to mount it. If i had mounted my resistors on the front side, i probably could have made it, but i would have had to go with smaller caps in some places. It still would have been close. Within a couple of milimeters. I advise you to do alot of planning if you're putting this thing in a 1590bb with a road rage (3005 version). The 3205 version should fit no problem.
