Can someone please explain how to interpret the following configuration diagram for the Avel transformer and which configuration is appropriate for the dynahi power board (forgot what the dots mean as well).

Second time trying DIY, but it's been a few years, so any help would be great!

what model # transformer are we typing about here?

For 120V (US) use, you will want the primaries wired in parallel (in series for 220V). The secondaries will be wired independently... one secondary to the positive bridge and one to the negative bridge on the PSU board. The dots indicate winding phase. The primaries you need to pay attention to this and wire both primaries in parallel and in phase, per the upper right diagram. I would also keep the dots straign on the secondaries (like the upper left picture).

This is the AT CE6558/1 model by Avel. I think it is the custom enclosed one made for dynahi via Head-fi a couple years back.

Thanks
