The current current standard for Europe is 220-240V, 50Hz delivered by a single live wire (brown), neutral (blue) and earth (yellow/green).
The national grids have not really changed, they just redefined the permissable standard. So, if Spain was 220V it probably still is.
If you got any tube gear do not convert it! This will be either expensive ( new input trannies) or bad (voltage splitter and dummy load). Once in Europe get yourself a mains transformer for a professional hammer drill (Hilti,Makita) as for some reason these run of 110V. They'll cost about 50-100 Euro.
Very popular with musicians using american amps and more reliable than the factory conversions.
