"While looking through the local (Jaycar) electronics store catalogue I came across a Magnetic Cartridge Preamp Kit (Cat. No. KC5433). It uses two LM833 Operational Amplifiers (op-amps) and cost $AU39.95. Naturally, the op-amps can be upgraded with higher performance versions. While I was satisfied with the Pro-Ject Phono Box SE I wanted to build my own phono preamp. I guess being an avid DIYer draws one to anything you can build yourself even if you already have a commercial unit. "
