Re: Re : A bit confused about potential problem / Voltage conversion

2007-05-22 by Einar Ekström

hi, been down that road before. i bought a wurlitzer from canada and 
had to use a step up converter. it resulted in massive amounts of hum 
unfortunately. for some strange reason the step up converters (in 
finland at least) are not allowed to be grounded so i had to connect 
a ground wire to the water pipes of my house! a bit tedious that was, 
and grounding to water pipes on gigs is not that fun... :)

the PSU on the moog source i have is "double wired" or whatever you 
call it. i have understood this is a quite common practice on mass 
produced electrical devices so that the company making them don't 
have to make different versions for shipping overseas. it was really 
a simple procedure, i had an electrician rewire it in 20 minutes, he 
just had to de-solder and re-solder two wires.
