I'd been talking to Duncan (Tubehunter) about building me a dedicated linear PSU for my Seagate (5TB) NAS drives (suppling music files to the RPi), to replace the stock switch-mode units, which like all items of that nature, chuck a lot of noise into the mains.
My thinking was that as well as reducing that pollution, which could have been having an adverse knock-on effect on my main system, ultimately receiving its power from the same mains supply, it may also improve the sonic performance of the RPi, so I bought all the necessary bits, gave them to Duncan, and this is what he came up with:
Total expenditure on parts: £165.00

Could it be the best linear PSU out there, with which to power a NAS hard-drive? I think so... It should form a formidable partnership with the Paul Hynes SR3DR-05 linear PSU, powering the RPi. Can't wait to try it out!
