Pännäri

The popular tube RIAA designed by Mauri Pännäri is continued as a discrete JFET implementation. This illustrated article guides you through the construction of the kit.

The RIAA preamplifier designed by amplifier guru Mauri Pännäri is a popular and highly regarded building project. The circuitry is based on two amplifier tubes and one FET transistor per channel. By changing the FET type, the series is suitable for both MM and MC cartridges. This guide provides instructions on how to build the RIAA preamplifier.
