The handwound transformer guys have a pretty crummy rep. There are a couple other small places that do one-offs and custom wound stuff. There is a place in Australia that has really good stuff and even with the shipping the exchange ratio is so favorable that it is worth checking into. Electra-Print claims to do custom work also. I have been discussing this amp for some time and it is nice when guys like yourself share their thoughts, since the trans. is the most significant aspect of a SE design I appreciate your input. My quandry is do I try a modest pair of OPT's and use them to determine the worth of the design or just jump in and bite the bullet with top drawer stuff. Ever see the Magnequest Iron for big tubes?
