We test all of our AC128’s for optimum gain and leakage current so that they are guaranteed to bias properly and sound great! Generally, with Silicon transistors in the Fuzz Face, you put the lower gain one in Q1 and the higher gain one in Q2 and you're off and running. Categories: Fuzz; Made In: United Kingdom. Some consider the AC128 to be one of the best transistors you can get for a Fuzz Face. PNP Complementary: PNP Complementary of BC108 is BC178 Replacement and Interestingly later reissue editions of the Fuzz Face did feature AC128’s, while there seems to be no empirical evidence for them having appeared earlier on. It is a moderate gain (90 typical) device with only modest frequency response. On the topic of transistors, can anyone recommend a good DMM with a transistor tester? I suspect that the average DMM assumes that there is no significant leakage - fair enough for a silicon transistor - but doesn't correct for the (sometimes enormous) leakage on a Ge transistor. Multiply by 100 and we have the transistor's gain. Parameters and Characteristics. $14. Besides being in the famous original Fuzz Face, the AC128 was used in numerous domestic electronic appliance, and certainly one of the most common European transistor. 25 W Maximum Collector-Base Voltage |Vcb|: 30 V Maximum Collector-Emitter Voltage |Vce|: 20 V Maximum Emitter-Base Voltage |Veb|: 5 V Maximum Collector Current |Ic max|: 0.
