Hello! I have put together the Harbinger Two, but,alas, it is not running like it should.
I had a soldier bridge between two pins on theLT1054 that I corrected. (The ic got a tad bit hot, so it was replaced.) I have it on 9v regulated bench power, and control wise, the volume is functioning as it is supposed to, the speed is not working, ie no change at either end of the sweep. The intensity, at either end of the pot produces no visible change,unless it's in the middle position. The gain and offset trimmer pots only change the brightness. Now, if I sweep my fingers over the 4 ldrs i get the swooshy goodness!
