Hi I know how to build power supplies, which is I why I also know that you don't need over-sized transformers on line level circuits and why you won't get full-wave rectification from just 2 diodes...unless you use an (expensive) centre-tap transformer. The performance of the PSU is predominantly determined by the smoothing caps and the voltage regulator. Using an oversize transformer to support a mere 3 amps at 5v is just a waste of money. There's also transformer ringing to consider... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
