Hi all!
After successfully DAC-END, Andrea and I designed a PRE-DAC, dac output, or used as a separate Pre, use tube 6h30, 6h6 ỏ 6DJ8 with the output impedance of around 1.2 K.

Especially I used Salas shunt for HV (SSHV), a PCB would be a perfect PRE including the tube and the source

Perfect for the support of the DAC output without using a rear Pre
You can se cricut and some image!
