I'm picking up one of the Analogue systems rs300 modules, so this will be expendable. I'd like to sell this really quickly. I'll sell for $125 shipped to continental U.S. Gene [Non-text portions of this message have been removed]

I¹m not even sure what the question is exactly...I don¹t know much about the electronics end of things, and perhaps someone might look at what¹s happened and have some ideas about what¹s going on. Or perhaps it¹s just bad luck? In the past few months I¹ve had 3 modules fail. A wasp filter stopped filtering (but would send the signal through), a logic module stopped working, and now, most disconcertingly, my a-154 isn¹t working properly. The top row of knobs and the various functions of the sequencer and the a-155 work ok, but knobs 2-4 on the bottom aren¹t working properly. The third knob has a limited warbly range, and the other 2 don¹t work at all. The module used to work fine. I also find that when I plug more than 1 or 2 outputs from a multiple, the signal degrades the voltage range that comes out from it is decreased (probably could be said a lot better. I hope that I¹m making some sense). Does the combination of these things point to some kind of underlying cause? Is this expected behavior from a multiple (I hope not)? Do I simply have no idea what I¹m talking about (kind of hope so). Discouraged right now. I really need the a-154. [Non-text portions of this message have been removed]

Hi Gene, My initial thought is for you to check your PSU is not overworked or failing in some way. Ideally check the voltages with everything plugged in and if your running below +/- 12V then that could be the problem. Some modules are a bit more sensitive to voltage drop than others.
