I am busy making a stereo USB/MIC/LINE mixer/preamp.
I learned from previous builds about pcb hum and interference and this one is dead silent despite having AC heaters.
Here is a picture of the main pcb. I have used a USB DAC module for the USB side.
The MIC/LINE input is mono converted to stereo. The USB input is stereo in and out.

An externally hosted image should be here but it was not working when we last tested it.
Here is the mixer in its enclosure.

Looks like nice work 🙂
I like the sound of the 12au7's.
They definitely sharpen up the sound.
