Uses silicon planer npn transistors, making it necessary to have temperature-compensating resistor in emitter circuit of first stage. Noiselevel is 66 db below reference level output with weighted measurement. Frequencyresponse is fiat within 0.25 db from 30 cps to 15 kc, and total harmonic distortionis 0.01% at 1.2 v output.- Transistor Manual, Seventh Edition, General ElectricCo., 1964, p 256.
