All of the toroidal transformers I have seen in Simmons gear are multi tapped on the primary. (keeps cost and
stock holdings down to do it this way) For the most part, in the later years they used the same transformer in all their designs again I guess for the above reasons. I haven't got any units open at the moment so I can't quote what colors are what (maybe someone else can). I will say that they tend to operate at their maximum power output ratings which tends for them to run rather warm (hot in some cases) This leads to insulation failures and PSU faults. I know as I kept a local transformer rewinder very busy quite a few years back. Every second unit in for fixing had a dud tranny.
If you are in the US and go for the step-up external transformer, please do ensure you get one rated with a high enough "continuous" output current.

Hey synth drummers!
is there a transformer tap in the SDS6 to switch between us/uk voltage>?
wondering if it needs a power transformer to become US.
