So I made the mistake of chosing a schematic for an amp before i looked at the power source it needs, and now im in quite a pickle. after I had ordered the parts for this amp, I realized that the trasformer which the genius designer of this schematic has recommended is non-existent, as in no company sells it. the circuit needs + and - 56 volts and the designer has recomended a 40-0-40 transformer (to my understanding, he means 80 volts center tapped).but all the transformers Im finding on mouser and such are at most usually 24v, some go up to 56v center tapped (wich would give me -+ 28v) and after that they jump to 120v c.t. which gives me +-60v, which is too high. basically I need a transformer that after regulating it and everything, it can supply + and -, 56 volts ( or somewhere in that range, preferably on the lower side), to my transistors.
heres a link to the schematic and instructions:

does anyone know what transformer I can use?? or can I wind one my self and if so what is the minimum amount of turns I need to have a decent transformer?
