Presenting a simple, versatile phono stage for moving magnet or high output moving coil cartridges using a bare minimum number of parts and the following features: Low parts count makes it cheap to build and easy to optimize. Wide choice of op amps. Just about any op amp can be used in this circuit.
5 maj 2004 · Very Simple Phono Stage. Only 27 parts for the whole stereo unit. User configurable gain 30-50dB. Standard value components, even for the RIAA eq. Allen Wright modded RIAA response.
