Default Tryin to find a transformer

I don't know where to find them. I'm going to do an LM3886 amp and want a 40v-48v ct 2A transformer. Or whatever I can use to do this and get a good wattage.

where are you?

A 3886 operating from +-30Vdc will push out a maximum of ~50W into an 8ohm speaker.
I would recommend a minimum of 100VA for this.
If you want to power two channels from one transformer then aim higher maybe 160VA to 250VA.
