Hi all. Can someone please advise me regarding re-using a Yamaha transformer stripped from an RX-V577? There are 2 wires that originally connected to the power switch, the yellow ones in the pic. Can I just connect the primary directly, and then measure the secondary voltages, or will the transformer not switch on, because the soft power switch that the yellow cable led to is not going to be used? Sorry if this is a lame question.

Try it.
Provided the primary voltage matches your supply you will do no harm.
I can only imagine the yellow wires provided power to the 'switch on' circuit, i.e. they are just a low voltage probably low current winding.
Take care not to short wires or electrocute yourself when testing.
