Been having trouble with Doepfer modules

2007-05-19 by Gene Schwartz

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.
