So the fuse just blew in my Doepfer LC-9. Mixed feelings a when a fuse goes, on the one hand it probably just saved all my modules, on the other hand I don't have any spares!

Anyway, the LC-9 has a 1200mA PSU, but takes a 400mA fuse, why is that?

Also, does anyone have a clue what the power draw from the the Livewire AFG and Vulcan Modulator are, can't find that info anywhere.

Without the Livewire modules I am at about 600mA so with my 1200mA PSU I thought I would be well within my limits.

I don't get much time to play with my modular and when I do this very frustrating

The fuse is on the input side (120V) and the maximum draw from the wall is 400mA. You gain current as the voltage is lowered inside a transformer.

Sounds like you might have a short circuit. If you have a multimeter, check the resistance of the power rails (+12 and -12) to ground. Make sure the rack is off when you do this. If the resistance is very low, <100 ohms, then there is probably a short. Unplug modules one at a time to find it.

I have an AFG and Vulcan in a Doepfer case too. I also have a 1200mA PSU and 3 rows full of modules (including the Livewires). I also blew the fuse once, it happend while I was swaping some modules, replaced it with another 400mA fuse and everything has been fine since.

I do not know what the power draw from the Livewires is, but I think you should be fine with 600mA plus the Livewires....

Replace the fuse and see...

Have Luck!

Oh oh! But what about the Chaos Computer? wink

Thank you guys for all your responses, very, very helpful as always!

One thing I love about Muffs is that no-one ever really gets flamed and there are no trolls to speak of, just helpful and friendly people thumbs up
