I thougt that single amp which have 2nd harmonic distortion will be low
distortional if it was in NFB loop. It's bad. So I decided to position them
in front of the amp.
Because harmonic distortion is precisely pure scale harmonics.

１ Ｊ－ＦＥＴ
２ Ｖ－ＦＥＴ
３ Upside down amp
４ Germanium amp
５ １２ＡＸ７
In this method distortion will go through to the end.
By hearing test 12AX7 was beyond of all.
１２ＡＸ７＋Kanzen amp
