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

[QUOTE="handsome, post: 1027506, member: 772"] You can substitute a toroidal output transformer into any PP amplifier design - as long as you implement some sort of bias servo. The difference between a 6k6 toroidal output transformer and a 6k6 EI transformer is the physical construction. The electrical characteristics will be the same, the performance of the toroid is likely to be better though. Its like substituting a toroid for an EI mains transformer of the same output voltage - the toroid is likely to be smaller and generate less interference but both will produce the same electrical result. So any design requiring a 6k6 OPT will work for you. [/QUOTE]
