NO!
If you use 20-0-20 then you get +-28Vdc because the 0V gives a reference.
The 40-0 gives 56Vdc and there is no 0V reference to split the 56Vdc in half.
You have been advised (by others) to avoid using a virtual earth for the power amp.
I now concur with this advice.
The reason I arrive here is that you would require a high current power amp to generate the virtual earth and having generated it artificially there is no guarntee that it will sound nice or even work stabily. A lot of development time and cost to avoid rewinding or buying a transformer.

Yes, after reading AndrewT's response again, I see my mistake. The 40V-0V secondary has no center reference to get the values I am seeking.
To total voltage across the AC pins of a rectifier may be the same from 20V 20V (centertapped case) versus a 40V 0V (standalone secondary case), but output voltages are referenced from different points...
Thanks again.
