Hello all. This looks to be a great site. My name is Rick and I started repairing and modifying audio back in the 70s. I rebuild preamps both tube and solid state. Mostly solid state.
At home I use Vandersteen3 Sigs with dual subs. Threshold Fet 9 pre and Forte 4 amp.
My interest in this site was a post by the co-founder of Amber. I wanted to find out if he had any schematics I could obtain.
