Kondensator an Kollektor?

"With Silicon it becomes very difficult to stick with the Q1 hfe of 70 and Q2 hfe of 120, because most Silicon transistors are way over 120 to begin with. Someone in Aron's Stompbox Forum said that placing a 100pF capacitor across the Collector-Base junction of the transistors in a Silicon Fuzz Face clone would help control the gain and oscillation, so if you decide to build this version, keep that in mind."
Kann mir einer sagen, was das heißen soll bzw. was soll ich da mit dem 100pf Kondensator machen nd wie geht das? Was ist überhaupt Collector-Base :-\ ? Wäre nett, wenn mir einer hier helfen könnte.
