Any advice on building a push-pull amplifier with toroidal OPTs?

[QUOTE="Qualityten, post: 1027383, member: 17776"] A year ago, I bought a huge power transformer from a Leak Stereo 50. And then I recently got a pair of toroidal push-pull output transformers. 6K6 primary impedance and 49% screen taps. The transformers sound pretty good just hooked up to my Mullard 5-20 monoblocs, but I'm thinking of building a stand-alone stereo power amp with these, using EL34 valves. Does anybody have any experience of using toroidal output transformers and any suggested circuits. I have read passing comments about DC imbalance, but don't understand these. [/QUOTE]
