Can I hook up a Yamaha RXV 493 AV tuner to an amp? I am using it power speakers throughout my house - via speaker selector box. Problem is my amp has rca inputs, but I don't have preamp or amp rca outs..

Oh, most all yamaha equip has pre-amp outs, maybe take another look there

First of all, here is the main ONLINE SUPPORT page for your model:

And here is a direct link to the ONLINE USER'S MANUAL for that model:

You may need ADOBE READER installed on your computer to read PDF documents.
You can download this free at WWW.ADOBE.COM if necessary.
Click on the DOWNLOAD ADOBE READER button on right side of the ADOBE home page when you get there, then follow the onscreen instructions to install the software on your computer.

You should just be able to use the TAPE REC AUDIO OUT (L/R) jacks on the back of the Yamaha 493 unit as your secondary amp's input signal. You might even be able to use the VCR AUDIO OUT (L/R) jacks as well. See page 8 of the manual for a detailed diagram of the rear connections on your set.

I hope that was helpful to you, good luck.
