This preamplifier was designed for low stage of stage of resistance options like going rings heads (MC). The schedule uses in identical three duble transistors SSM2220 or MAT03 and by creating a diferential company keeps noice low. Linking this company before part of a OP27 amp we acquire even decreased disruption. Also the operate we use PNP rather NPN transistors is cause they have les low reliability noise. This Output must conected to Moving Magnet Preamp input.
