Notes: Karsten's first oscillator design, no. 1 of 1 built, date unknown, but likely late 1990's. My first Karsten, procured in a trade with MooseMan...leading to many others from varied sources. Characteristics of this prototype can be seen in Karsten's 2nd generation commercialized oscillator that followed.
