Classic Quad 405 Power Amplifier Restoration

I recently purchased a classic Quad 405 power amplifier to use as my main stereo amp. It sounded fantastic even before my overhaul, read on for the gory details and, for some extra reading, check out my Quad 405-2 review.

The Quad 405 is revered by many, even 40 years after its release. It’s not hard to see why, the 405 does an amazing job of just getting out of the way and playing music.… Read more

Kenwood KD-600 Direct-Drive Turntable Service & Set-up

In this video, I explain some considerations when correctly setting up a turntable like the Kenwood KD-600.

This particular deck 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 gear, but clearly not everyone there knows what they are talking about.… Read more

Audiolab 8000Q Preamplifier Repair

Lovely little preamp the Audiolab 8000Q. It’s really only let down by poor quality factory-fitted parts, particularly the capacitors.

Amazing Kenwood L-1000 Hi-Fi System in for Service

Wow, would you believe I’ve just serviced a complete Kenwood L-1000 hi-fi system?! Just incredible gear, beautifully constructed, with stellar build-quality.

The Kenwood L-1000 series of components are becoming rare now, so to find a complete system in the hands of its original owner is something pretty special. This stack of gear consisted of the Kenwood L-1000M power amplifier, L-1000C preamplifier, L-1000D CD player and L-1000T tuner.… Read more

Yamaha CA-610 and CA-710 Integrated Amplifier Service & Repair

Recently, two friends with lovely vintage Yamaha CA-610 and CA-710 integrated amplifiers sought my assistance to have them repaired. One was dead, the other was not working well.

The Yamaha CA-710 had blown one channel. One of the original output devices, a Sanken 2SA745, had a collector to base short and it had taken out one of the driver transistors.… Read more
