DIY tube/phono pre in the same case as my DIY dac?
I am building a DIY DAC, tube phono pre, and tubed grounded grid tubed pre. The case is 8x14x17 There is a 1/4" wall to seperate the transformers from the audio section. Can I mount the DAC below the tubed phono pre? I was thinking of a switch that would shut one off while the other is in use.

I don't think the Phono pre would interfere with the DAC, but the DAC may introduce noise into the Phono stage.

So, if you have a switch to turn it off when listening to your Analogue source you shouldn't have any problems.

Is the DAC itself in a separate screened box? If not this could help too?

Can you test it temporarily without drilling the case and mounting permanently to see what the noise (if any) is like?

I am going to have a switch to choose which input is being powered. A screen would be hard to setup.

Any luck/progress so far, ben62670? I'm also interested in a Tube DAC + Phono. Is there any brand selling out there?
