If I had to build one modern tube project then this would be the one.

Due to the slightly complicated design a PCB is helpful which do not seem to be available right now. Maybe once the PCB is again available for sale I might take the plunge.

What tubes you are planning to use? ECC88 family and ECC81 should be a good combination with enough gain to not need a line stage.

First stage I want to use E88CC or 6922 and second stage is 12AT7 total gain of this preamp is 41db (28+33.6-20) approx my Cartridge is Audio Technica AT120E which deliver 5mv so i think 41db is sufficient for today's modern solid state amplifier.
