So I had an old home receiver which broke down so i took out the large transformer 6800uf caps and rectifier. This receiver put out 60 watts out of each chip so from my many hours of being on google in the past, the chips should require +-35v, and because of the increase in voltage after rectification and decoupling, this transformer should put out 24vac. 12-0-12 when i tested the transformer is was putting out 30-0-30! after the rectifier it was putting out above 70 and the 6800uf caps are only rated for 50v! And i looked inside the receiver before taking these parts out and found it to be just the simple split power supply, nothing else. for my project i need around 30-40v split supply. I cant think of a real way to drop the voltage down half of what it is but i did have an idea of rectifying between both the 30s and 0 giving two 30v outputs, then i would put them in parallel. but it continued to give me 70 for some reason. anyone have an idea for getting what i need out of this transformer?
