I need to know how find the correct wires on a transformer with multi pri taps. I have a transformer that can work on PRI 120vac, 220vac and 250vac. There was a switch to select the proper input voltage but the switch was removed and now I am stuck. I would like to know what to do to get the transformer working on 220/250 vac. The colour of the wires that goes in on pri side from main is:
ORANGE
WHITE
BLUE
RED
BROWN
YELLOW
I hope this could help in a way. The transformer is in an audio amp. The transformer is a TAMRADIO. I don't find any data about it. I'll appreciate help. Thanks
