Audio Note line preamp question

rotation · 07:58 PM

Hi,

i would like to build Audio Note M7 line stage. I searched Google and this forum, but can't really find out which versions of M7 AN made and what tubes they used. I found out that it was probably Kondo and not AN who made M7 as a line preamp only.
Can someone please explain a bit of history about AN M7 (or whatever it was called, it's very famous and many people built it) line preamp? At this stage i'm more interested in amp circuit, not psu.

Thanks guys. I found that thread but i'm a little confused. As i understand it AN is now using one triode of 5687, anode out, rectifier is 6X4. The same circuit as on schematic in thread rfbrw just showed me. Am i correct?
I'm sorry if my question is stupid, there is too much information on the internet now :-)
