The operative word is 'yet' !
Meanwhile I enlarged your amp to have a better look. It is beau-ti-ful.
It sure is beautiful.....simple and elegant.
For the people that obsess over not having any noise in the back round...one tube mode provides this....always black as midnight.
Two tube mode is much more dynamic, more everything...slam impact & dynamics...much more authority...as with anything with tubes and transformers, can at times have some back round noise....it disappears with the music.
I know some people always want their amps to be dead silent. Probably best for them to check on some SS options....but they will be missing some wonderful tube goodness.
