H1+H3, H2+H4 for the primary.

But i know your aware of this, this is only for other readers.

This may work for "electrical" transformers (ie: those intended to be
installed by electricians), but I have rarely seen an "electronics"
transformer (one an electronics tech would install inside equipment)
labelled like that.

The best way, regardless of the transformer marking or colour code, is
to get a data*** for the transformer - it should indicate which
wires or terminals are the start of the winding, and may even indicate
the corrects connections for serial or parallel operation.
