hi dsavitsk
i was looking at the less-pressivo thread over at headwize, and that amp looks sweet. I like original design too, but too much money
i was curious with the balanced schematic why you put the cap between the halves of the transformer with no ground connection rather than at both ends with the centers grounded. it is still parafeed, and no current flows in the primary, but why drop the safety feature of having the transformer grounded?
