Anyone famaliar with the manufacturer,and in particular this pre amp.The credentials and testimonials seem impressive.The advertised 10 day audition is appealing.
I obtained some tubes to play with in the AH preamp and will report: They include a quad Siemens E188cc from the year 1960, a quad of Siemens early sixty cca, and a quad of Telefunken early sixty E88cc. From my want ad on a-gon, offers are still coming in. If you have interest email me and I will pass you the person's selling information. For example a pair of cca under RCA label for $150 ANOS. I have not researched these offers so do your own diligence. Peace Joe
