High Current Power Supply Answered

For a project totally nonrelated to my tesla coil I need a way of regulating a voltage down to 36 Volts at 8 amps. My transformer (or a bunch of transformers hooked together) is suppose to have an output of about 38 volts at 8 amps, yet the voltage (with no load) is actually around 60 volts... Basically I need a way of regulating this voltage. For saftey, lets say the max input is 70 volts and it should be able to handle 10 Amps. The output voltage should be 36.

Regulators like the LM317 should have high current circuits on the data sheets. You'll need a few more components, of course.

woah woah woah the lm317 doesn't have a maximum input voltage, just a maximum difference!?! That might just work great then.

Yeah, the differential between the input and output voltage is 40V... Max input voltage @ 36V output = 36+40 = 76V.

36V output is just within the specs.

alright, I'm going to go with 8 lm317 in parallel, to give some wiggle room
