For 600-ohm source, 3-db response is 0.5 cps to 700 kc, with voltage gain of 10.5, using common-emitter direct-coupled amplifier stage after fet stage, with 26 db of feedback. With 1-meg source, upper limit is 20 kc.-E. G. Fleenor, Low-Noise Preamplifier Uses Field-Effect Transistors, Electronics, 36:15, p 67-69.
