No, I would agree that an oversized transformer isn't 'the answer', but if "big electroylytics" are, then it would be simple enough. Buy one of the many linear supplies offered on ebay, and just add a large amount of capacitance to it.

Below is a link to my take on the Belleson voltage regulator. As noted, I was running the Slee phono stage with two large motorcycle batteries in series, as a 24 VDC supply. Many think of batteries as the holy grail of DC, but when I replaced the Slee's internal 7818 (+18v) regulator with the Belleson regulator being fed by the battereies I got blacker backgrounds, more detail, and more musical involvement.

Edit: I'm not suggesting that a quiet regulator is the sole answer either. As noted, I'd locate a known good schematic, then build the power supply with quality parts.

Good luck with whatever you decide to do.
