I didn't want to derail from the Scottl Ampfest thread, so I thought I'd post this in a new one. Everyone seemed to agree that the Bludotone "Big Iron" amplifier that I believe was Laz's was a huge favorite, and I was wondering if anyone had any information about this. What's the advantage of using larger, higher voltage transformers in an amp of this style? I've been strongly considering doing a scratch build based on the D'Lite specs and was wondering if the Big Iron is worthwhile and what the science behind it is. Any of you amp geniuses out there?
