Myself and a few others have been posting in a C1 thread and we wanted to break away from doing so by starting a thread about the C2 Kenwood Basic Preamplifier so the information would be easy to find if others needed it. We were going to detail the upgrades and restoration to this unit a bit at the time. . I would like to thank @Leestereo for starting the C1 thread that this thread was named after. You will find a plethora of fine information and facts about both units here : http://www.audiokarma.org/forums/in...c-c1-preamplifier-restoration-upgrade.609337/ More to come..Thanks for watching !
