Default reading schematic - power source

I have a schematic showing connections from a transformer to a circuit
board. Each connection reads: "12.6VAC" followed by the connection id
(in this case "TP7" and TP8"). My question is: would the transformer
in this situation be called a 12.6VAC transformer, or would these
voltage markings on the schematic indicate the voltage for each
lead?


This came up recently when I was looking for a replacement trans
online, and the transformer, rated at 12.6VAC had markings on its
underside that said "6.3V, 0V, 6.3V".


If the transformer is centre tapped and that connected I'd expect it to be
12.6v per winding. Usually to provide a symmetrical power supply.

It's common these days to have two separate windings on replacement type
or general purpose transformers. That gives the maximum flexibility of
connection.
