Default Help needed for 6H30 output schematic for DAC

I am left with a pair of 6H30, 6X4WA and 230V/6.3v transformer from a failed project which I would like to use it to build a tube I/V stage for my AD1865 DAC.

Can any kind soul provide me a 6H30 schematic that works and sound good?

Have a read through this.

It seems that you would have to use your DAC in voltage output mode.
The 6H30 tube is a variant of the 6N6p which probably has insufficient gain, for a current output DAC.
