Can someone suggest a turntable shelf?

A wall shelf is a great DIY project. Home Depot has brackets and the shelf itself can be made from all kinds of different materials. Lots of clues on the forums. If you don't want to go DIY, the Target shelf is pretty good for the money and you can tweak the platform. Finally, do not use any kind of glass as the platform.

Glass shelves are used on some very highly regarded stands including those by Naim and Wilson Benesch.

I double and triple Thorman----don't even think about this if you can't attach it to studs!!!

I've never seen a Scoutmaster placed on a shelf. I worry that this project will be a waste of your energy. I'm not worried about wasted money, because if you can afford a Scoutmaster, you can afford a shelf. But it takes effort to find studs and bolt into them. If your Scoutmaster isn't floating your boat now, a shelf will not provide a silver bullet.
