RCA Input Source to Two Outputs?

I am searching for a device that will enable me to switch between one source (Node 2i) and run the signal to either my Yamaha AS1100 or to an Elekit tube amp. I see plenty of devices that allow multiple inputs to one output, but can't seem to locate the opposite...



I wouldn't mind building one myself, but I'm not that experienced with electronics to both develop and build. Any kits? Or just a device I could purchase?


Thanks!
