IMHO, I still believe that is too much transformer. The 50VA Avel puts out 830mA. Less than half of that is more than plenty.
If you are going to buy an Avel, why not use the 30VA Y236107 that Alex recommends on the EHHA Rev. A BOM? As Sachu points out, you can probably get by with the 25-0-25 part as well (6106).
Unless you are building a four board solution, 30VA is plenty, especially for the Avel product.
EDIT: Just to be clear, since you have referenced the sigma22 web site, this amp has it's own built in power supplies. Unlike the original EHHA, there is no sigma22 required for the Rev A version.
