I was bored so I made a D200 concept drawing.

Let's take a look at this in depth. An all tube DAC, without the benefit of miniaturization that integrated circuits or even transistors have provided, would probably need a building as big as the Smithsonian Air and Space museum in downtown DC to house and would require as much power and HVAC to run.

But I may have misunderstood what you were asking for or took the idea too literally.

There are at least a dozen or more Tube DACs out there. It is quite doable.

Yeah but they all still use a DAC chip. ESS, AKM etc. It would probably be impossible to make an ALL tube DAC since ICs are just too complicated and like BlueSky said it would probably have to be the size of a building if they did.
