Default Mini-Me second edition tube phono preamp

Today i tested the second edition of the Mini-Me.
And it sounded very good.
This design has only one 24v power supply. And is very cheap to build for a tube MM phono preamp.

Some spec's:

- Amplification = 175 x(44.5db)
- THD = 0.15%
- Noise = -72 db
- RIAA = < 0.5db
- Board size 100 x 100mm

The power supply is a cheap 24V smps.

Schematic is the same as the first Mini-Me with a view adjustments. Later this week i will publish the new schematic and pcb design.

The tubes i used are 6N28b-v.
