90s KLON TL072CP Low-Noise JFET-Input Op-Amp Chip

Build your own KLON with these same chips made to use the original Klon under the black goop.

These are the same chips in some of the most coveted and outragouesly priced Klon Centaur pedals. It's not rocket science, but it is science...

The JFET-input operational amplifiers in the TL07x series have low input bias, offset currents and fast slew rate. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio preamplifier applications. Each amplifier features JFET inputs (for high input impedance) coupled with bipolar output stages integrated on a single monolithic chip.
