I have this transformer, and i want to get 27V output. i don't know what's inside, but i just have the product. it's a 15/12/0/12/15 vac center tapped transformer.
The question might be dumb, but is it able to connect those 12,15v wires in single transformer to get 27 volts?
if it's not possible, will i be able to get 30v by putting one more transformer and connect 15volts in series? it's a 0.7A transformer.
