Larry your phono amp still needs attenuation throught the preamp, how would you control the level output. The output of your phono amp will go into one of the inputs so you can control the volume.
go with v3.
all of these parts can be had at your local radio shack, you will need to make the enclosure for it though, i suggest red oak or MDF veenered with red oak...should of got the old PL knobs so you could used on you new preamp build.
