Mu-tron II Phasor Mod

[jettrocker]

Hi. Just bought a Mu-tron II Phasor on eBay. The pedal run on 110VAC but I live in Sweden and we have 230VAC here. I would like to avoid having a big voltage converter on my pedalboard so I wonder if its possible to modify the pedal to run on 230VAC ? Is it doable ?

it might be as simple as finding the right transformer

do you have a voltage converter that you could plug the mutron into and then measure what's coming out of the transformer secondaries?

These guys seem to specialize in Mu-Tron, http://www.lsound.com/index.htm#Mu-Trom Service , maybe they'll know.

Personally, I would go with an external transformer, and keep the pedal stock. Besides, a plug-in 220 to 110 travel converter is really not that big, and this pedal really doesn't consume that much power. At a 120 volts, 5 VA is about 3.5 watts. A small travel tranny should be fine.

Cheers,
Dino

a bit offtopic, but that box is my alltime FAVOURITE phaser!
so creamy!

I have no electronic skills so I need help with doing the mod if Im gonna do it.

Thanks for the lsound.com link.. will send them a e-mail.

Maybe a small travel tranny could be ok..  of course its nice to keep the pedal stock.

Two options, as near as I can tell.  One is to find a suitable 24VCT transformer.  I think that's what it says on the schematic, and that voltage would be about right given what comes out after the regulation.

The other is to find one of those tourist stores that sells step-down transformers to convert your 240 wall AC to 110.  Given that the unit draws very little current, it shouldn't be too hard to do that.  I can't imagine the Mu-Tron II draws more than the average electric shaver; something for which there almost always is a transformer.
