Description: A 10cm x 10cm circuit board on which you can build a highly accurate Moving Magnet phono preamplifier. Why buy an expensive turntable and connect it to a mediocre preamp? Conformance to the RIAA curve is within 0.1 dB from 20 Hz to 20 kHz.CCIR/ARM noise voltage around 0.26uV.THD better than 0.01% easily achievable with LM833s, and a lot lower with OPA2134s etc.Uses 2x very affordable LM833 dual op-amps or a variety of other ICs such as NE5532, TL072, OPA2134 etc. Choice of solder to board/terminal block/RCA socket input/output connectors.Extensive power supply noise bypassing.Convenient 4x 4mm mounting holes.A well thought-out fire-resistant double-sided circuit board designed in the UK. The circuit can be seen in the AN-346 High-Performance Audio Applications of the LM833 datasheet.RCA socket sourcing data will be given in User Guide. Bill of Materials. 4x 5mm 2-way terminal blocks OR 4x RCA phono sockets 2x LM833 DIP8 IC (or compatible). 2x DIP8 IC sockets (strongly recommended). 2x 47uF electrolytic capacitor. 4x 100uF electrolytic capacitor. 2x 2.2uF electrolytic capacitor. 4x 100nF ceramic capacitor. 2x 33nF polyester capacitor. 2x 39nF polyester capacitor. 2x 47pF polyester capacitor. 2x 47k resistor. 2x 499R resistor. 2x 80.6k resistor. 2x 8.45k resistor. 2x 2.37k resistor. 2x 49.9k resistor. 2x 1.54 resistor. 2x 3.32k resistor.
