Abstract

PURPOSE:To improve the frequency characteristic and S/N to improve resolution, by conncting a transistor for emitter follower to the output end of the first-stage amplifying circuit and by connecting this circuit to the next-stage amplifier. CONSTITUTION:The emitter follower output part consisting of transistor Q2 and emitter resistance R5 is connected to the drain output end of preamplifier 12 stored in yoke assembly 11 to make the output end of preamplifier low-impedance, and the output end is connected to the input end of negative feedback type constant-current amplifier 15 through output signal lead 16. This negative feedback type constant- current amplifer 15 feeds back the output to pre-amplifier 12 through feedback resistance R4 to improve the frequency characteristic.
