Provides 1 w output with only two transistors. Highinput impedance (above 10,000 meg) of fet permits direct drive by high-outputcartridge, while MJ2252 npn silkon transistor operotes directly from 120 v d-c output of simple power supply using Motorokt 1N4004 sur melic silicon rectiner.Volues are:C1-100 mfd; C2-0.1 mfd; C3-100 mfd, 3v; R1-330; R2-10K; R3-3K; R4-1 meg;R5-5K; R6-l00K; R7-33.-D.
