I did read about balancing the bias currents for toroidal output transformers, probably having to use some sort of bias servo. It's starting to be a bit much for my application.

I've not yet come across a sensible (reliable ?) servo arrangement akin to current mode smps cycle per cycle which can steer through the AB1 function with worstcase conditions. There are some circuits but all have massive complication. Workin' on it.

I use an EI Majestic output transformer (UK) which has response -3dB down at 15Hz & 45Khz. This item isn't cheap now that european currencies are ramped up so high against the $$. Absolute Pot Crazy.
