View Whadda Velleman Project Kits Range

This 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 OPA2134 and make other component value tweaks for improved performance.
