:-/hi i have a problem i have a ddrum 4se brain which i got new from America i want to change the voltage to UK 240vi have opened it up to see if there is some sort of switch to change but not someone somewhere on this forum told me how to change it by i think cutting/unsordering some power supply wires sometime (/ few years ago) but i didn't do it then and i have lost the paper work on that subject . CAN SOMEONE HELP ME PLEASE !!

If you decide to go with a power converter, just make sure that the output power it produces matches up with what the modules needs.
You could end up with some unpleasant results if the amperage rating is too low (US ddrum module is designed for 120V on a 15A circuit).
I fried a Zip Drive power supply years ago from this...

Hi, There's jumpers to the right of the power transformer (if looking down into the unit with the front facing you). It's marked up on the PCB, two jumpers for 110V or just a single one for 220V (230V). Here's a photo. www.mediafire.com/?v6vudyh20l35x48 |

I would strongly recommend that you also verify the parts you have are rated for 110/120V before doing this. I noticed the schaffner inductor pack (large black module on the other side of the cord connector in that photo) is for 220V and 0.8A. I haven't opened mine up to check, but I think it would need to be rated at 120v and 1.6A for use in the USA/Canada.

I have an American ddrum4 that i've been running on 240v through an ac to ac converter off ebay outputting 100ws, it was about £10. Its been running like this for many years often just left on with no problems to date.
I didnt know about the jumpers inside but am a bit reluctant just in case. The converter doesnt bother me although it would be nice to just have a plug. If anybody can shed more on the multivoltage jumpers inside i would be grateful.
So to the original poster a 100w transformer will do the job nicely.

Hi There,
After so many happy years using my DDrum SE4 module, it now looks like the US Power supply has died. I'm trying to source a UK voltage power supply that will fit.
Any suggestions would be greatly appreciated.
Thanks
Richie

So I've switched my 110v over to 240v this morning - pretty simple job: desolder two bridges, resolder one of them in the 240v spot, switch out fuse, change plug... voila!
Fuse was the biggest pain since mine uses 32mm 125ma slow blow which are hard to find here. I believe some use 20mm cartridges (assume those set up for 230/240v from the off).
Parts wise everything is specced fine - it's just the fuse that isn't. They're designed to just need the PSU switching over since they are sold in different voltage regions.
Incidentally these use the Nord lead 2 PSU, which I believe is used on lots of the older Nord stuff like the G2, Wave etc. Later versions have a switch to select voltages rather than a jumper and are probably (possibly!) interchangable.
There's an old thread on ekectromusic that outlines this for the Nord lead and goes into plenty detail - worth a search if you're going the same route. Cheers!

Ken Ah, I didn't I'm afraid, though here's the bit on the PSU board that needs the jumpers changing and the setup for each power zone:  ![]()  The top one is the 220v config (suitable for 240v) while the bottom is 110v. It's just a case of desoldering whatever is set up and resoldering to what you want and changing the fuse - 125ma slow blow for 240v and I think 250ma slow blow for 110v. |
