how do i make a 50V power supply?

im new to DIY audio and it might seem like a common sense thing but i dont understand how to get a 50V power supply. more specifically the transformer. i dont know exactly how they work as in the setup for the power supply ive looked for a transformer that has an output of 50v and i havent found one. so im either headed in the wrong direction or im looking in the wrong place. im starting to tihnk that you might have to add some volatages together or something lol. i really have no idea. try and take it easy on me im new. it would be a huuuuuuuge help if someone could direct me in the right direction. thanks

Look at www.hypex.nl.

could you just hook up like two 24Volt transformers in parellel with the AC line and then hook up the outputs in series to get 48 volts or would that be ceating to much current? i dont want to have to get a torodial transformer

I presume you want + and - 50 volts DC for an amplifier project. If so, you don't want a transformer that puts out 50 volts AC. When you rectify and filter the transformer output the DC voltage will be near the peak of the AC waveform, which would be 70 volts. In practice there will be some loss so the DC will be a bit less, but still far from 50 volts.

Your best bet is to get a packaged ready-to-go DC power supply, such as those available from hypex. Many other manufacturers also offer power supplies. You need to know how many amps it must supply as well as the voltages.

Can you use a variac (variable transformer)and monitor the output.
