I understand this transformer can be rewired for operation on 220v by connecting primary windings in series?
Have a look a the picture (love it when manufacturer have a scheme on it like on vintage gear)
I would appreciate a step by step guide on how to proceed. My electronics understanding is limited to changing output devices, caps and simpler stuff.
Do the secondary wiring need to be changed as well?
It´s a McCormick DNA 0.5

Secondary wiring is ok.
Primary needs that you connect 0V black and 117V white/red wires together. black/red and white are 220V primary than.
