In this video, I explain some considerations when correctly setting up a turntable like the legendary Kenwood KD-600. This particular KD-600 came to me very poorly set-up. The deck's owner received some very bad advice from, of all people, Ortofon! I'm a big fan of Ortofon cartridges, but clearly not…
I'm sure every regular visitor to my site knows just how much I love the old Kenwood KD synthetic composite turntables, especially the KD-600/650 series.

In this article, I discuss the history of the gainclone and building my own dual-mono LM3886 chip-amp/gainclone amplifier. The LM3886 is one of Texas Instrument's single-chip monolithic amplifier integrated circuits. It's almost an entire amplifier-on-a-chip, with only a few extra parts required to build a fully functional, high-performance amplifier. The…
