OK... I am trying to get a PSU together to power 8 (or more) pres. I started searching for high-current regulators and found the LM150 and LM338 (3A and 5A respectively) but I cannot find a negative equivalent. I think you could use a positive wired "backwards" to produce a negative rail (ground the output and take your output from the ground pin) but is this the only way? Why would national (or whoever) not produce a higher current negative regulator?
The reason I am looking at these is they are easy to implement and have a small parts count. Any ideas as to how to build a (relatively simple) bipolar +phantom PSU that could put out 5A? Judging from all the Neve builds using multiple PSU boards, I think this is something missing here, so if someone can help me put it together, I'd be more than willing to share.
TIA
