    Altronics and Jaycar stock and sell the RD-65A. This is the dual output version, +5V and +12V. They don't have the RT (triple output) series.

    I prefer Mouser / Digikey as they're cheaper.

    Yeah I'm not a fan of converting a schematic into a PCB. I like creating / having a schematic for reference but I prefer to create my own nets and hand route.
