Funnily enough I recently had occasion to find that out - I wanted a quick cheap and cheerful 110v power source and thought the transformer for my LPL 7700 might have a tapped transformer. It doesn't, it's a simple 220v in/12v out. I then looked at a Meopta 12v transformer labeled "220v" and found that it had two primary windings wired in series. So that would be a simple conversion to 110v if required - and it also provided me with the 110v I needed by using the primary winding as an auto-transformer.
