Fiddling with deadly currents

A while back my good friend Niklas from NOR and Norator visited me here in Stockholm for an epic synth weekend (featuring amongst others Kraftwerk and Cold Cave…) and helped me modify my Doepfer LC9 boxes from north american voltage (110v) to the swedish (230v).

Its a relatively simple modification if you’re handy with the soldering iron and know the basics of electrical engineering, but since I wouldn’t put either on my resume Nicklas volunteered to perform the procedure.

Below are some shots from the operation.

Start by loosening the screws in the back…

That hold the cover for the actual PSU (the one that say you will DIE if you tamper with it…)

And that’s it! My LC9 boxes are now fully compatible with the swedish electrical standard :). Many thanks to Niklas for taking the time!

You can find a document that explains the necessary steps near the bottom of the following page on Doepfer’s website: http://www.doepfer.de/faq/a100_faq.htm#Modification%20mains%20voltage

  1. That was an awesome weekend! And I’m just happy to be able to get your modular going again! :-) By the way… have you installed and tested the CV-tools-module I made for you?
