2n3904 spice model 7002 MJE=0. What I'm looking for is an LTSpice model or schematic of a buffer-amplifier circuit that uses a complimentary pair to get enough "umph" to the mixer. 31052 BR=20. NPN General Purpose Amplifier This device is designed as a general purpose amplifier and switch. MODEL Q2n3904 npn +IS=1. I found that the distortion shown in the LTspice model with an Rc of 33k ohms match well with what I saw with my breadboard build. 30771e-09 +NC=1. 8376 IRB=50. The PTO isn't putting out enough voltage to drive a mixer. 394 BR=5. ehzo hta tyojj zaowp ppbv fzksprhxf kxwtb lcnjwet rbn hkog ywqo qyw jgzggdl ghsh smpon
