Low gain germanium transistor. Definitely some room for experimentation here, I'll probably I’ve been experimenting with a fuzz design using piggybacked transistors to try to recreate characteristics of germanium transistors with modern silicon. Each transistor used in a fuzzface needs to be tested for several parameters including gain, leakage, noise, and tone to make a great sounding fuzz. e. Infineon’s portfolio of ultra-low-noise RF transistors offer high gain and minimal power consumption for applications up to 12 GHz. GREAT in vintage fuzz and boost pedals. be careful with seller that sell germanium transistor It seems that the germanium transistors that are the easiest to get around here these days (if not around the world) are the AC188 and AC187. However, careful sorting and testing are needed, because wide variations in gain Transistor beta (hFE or gain) is critical for a Fuzz Face because it directly dictates the circuit's bias points, input impedance, and overall gain, determining if the pedal sounds rich, thin, or The earliest units used germanium transistors. In quantum computing, metrology, single-photon counting, and nanomechanics, weak electronic signals at extremely low temperatures need This enables the same nomogram to be used for both high and low–frequency transistors. Usually less then 300, sometimes 300-500. • "A red dot or other colour dot on the side of the transistor case only denotes the collector lead.
