AB  - Vacuum tube preamplifiers for use with dc-biased condenser microphones have two drawbacks: They require multi-wire cables and they are usually noisy. Using the high voltage transistors available today, a two-wire -cathode follower- type of preamplifier is practical. If a low leakage FET is used at the input, bias resistors of 1000 megohms or more become practical, substantially reducing the input noise level. The design of such a preamplifier, with its associated power supply, is discussed.
