Sharing amp inputs between two pre-amps

Tried searching for this in the forum but came up empty.  Limited space is forcing me to share my system between my TV and audio system.   The amp is solid-state with a single pair of inputs.   I currently have a solid-state pre-amp hooked up for both needs but I have a tubed pre-amp that I would like to use for the audio portion (CD / vinyl) only.  Would it be possible to use Y-adapters on the amp inputs to share them between both pre-amps?  Only one pre-amp would be on at any time.

Thanks, Al, for your thoughtful and detailed response.  I will probably abandoned the idea rather than take a chance on damage to my gear but I will definitely have a look-see at those switch boxes you referenced.  Cheers.
