is possible?

An externally hosted image should be here but it was not working when we last tested it.

why?

and I don't think the 3534 will drive 4 mosfets from each output very happily...

EDIT: If one transformer won't give you enough power, you would be better off using 2 seperate controllers to drive the 2 transformers... this way you can use one transformer for the positive rail, and one for the negitive and set them EXACTLY the same...

Indeed, the 3524 isn't able to do that. You should use a BD-transistor at the outputs (EA, EB) to switch the IRF's.

See http://www.sound.westhost.com/project89.htm for that.

whatever you end up doing, I suggest you make a small switchmode powersupply first and get it working, and know what you are doing from a little experience... 🙂

U're absolutely right. I've missed them in the schematic...

Already done a working one with +/-15 and +/-21 output from it my question were if were possible to do my proposed schematic with bd as Vigier say!
