The K2573 Stereo RIAA Pre-Amplifier is a SELF-ASSEMBLY electronic kit for MD phono pick-ups.
The circuit uses a TL072 Low-Noise JFET-Input Operational Amplifier IC. These devices feature high slew rates, low-input bias and offset currents, and low offset-voltage temperature coefficient. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio pre-amplifier applications.
The kit makes a good platform for upgrading. For example, you could change the TL072 supplied to a Burr Brown OPA2134AA and make other component value tweaks for improved performance.
With the spread of CD players, many amplifiers and mini sound systems no longer have a phono input for a record deck. This little phono preamp will solve the problem and make your expensive vinyl record collection usable...
