I am attempting to build a power inverter from a magazine article and would like to use one of several transformers from my spare parts collection. I have the following questions: 1) How careful must this selection be made, i.e. is it possible to use most transformers with the proper turns ration as long as the current rating is within my limits? 2) Most of my scrap transformers have at least 8 wires coming out (some have more) - what are they all for? 3) Are transformers intended to be used one way only (step-up or step-down) or can I reverse them. For example, can I use a 120 VAC primary/ 12.6 V CT secondary with the power inverter? 4) What exactly does the VA rating indicate? I know these seem like elementary questions, but this is the first time I'm dabbling with transformers. Any help will be greatly appreciated. Regards, Jeff
