McIntosh C220 Preamplifier Repair

I’ve just repaired this lovely McIntosh Laboratories C220 preamplifier. This seemingly high-quality preamp fell victim to a growing problem with newer gear – modern Pb-free production processes.

The McIntosh C220 preamplifier is a hybrid tube/transistor based preamplifier, featuring a phono preamp and microprocessor control. It’s a well-made unit, though not like the McIntosh of old. The board is high-quality fibreglass and internal layout is clean and tidy, using nice parts.… Read more

Quad 44 Preamplifier Service

I’ve just serviced a Quad 44 preamplifier. In this article, I’ll show you what the 44 looks like inside and explain some of its features.

Along with a Quad 405 power amplifier, I recently serviced this Quad 44 preamplifier, both owned by the same customer. I’m told he purchased them after a chat we had about resurrecting his KEF speakers, and purchasing some Quad gear to power them!… Read more

Audiolab 8000Q Preamplifier Repair

Lovely little unit, the Audiolab 8000Q preamplifier. Unfortunately, it’s let down by poor quality factory-fitted parts, particularly the capacitors. In this article, I repair this very nice pre-amp.

This Audiolab 8000Q preamplifier came to me with a fault which would see it sometimes take a long time to turn on. I’m talking a really long time – it would sometimes take up to 30 minutes to become operational after turn-on.… Read more

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

Luxman C-5000A Preamplifier Repair & Restoration

A while back, a customer came to me with two pieces of equipment he wanted to have restored – a gorgeous Luxman M-4000A power amplifier and a matching Luxman C-5000A preamplifier.

I restored the M-4000A here. This post looks specifically at the C-5000A, a rare and beautifully built preamplifier, from the somewhat enigmatic manufacturer, Luxman.

The Luxman C-5000A is indeed rare, so rare in fact that, despite extensive searches and contact with the Luxman Yahoo group and the Luxman Vintage Audio website, there are literally no service manuals available for the ‘A’ series models.… Read more

Primare R32 Phono Preamplifier Review

I have been lucky enough to have a brand new Primare R32 Phono Preamplifier on loan to audition over the last few weeks and I wanted to share my experiences, by writing a proper review.

The Primare R32 phono preamplifier is designed in Sweden and is a fully discrete, solid-state, DC-coupled, class-A phono preamplifier. The R32 has three gain settings, allowing it to work with the vast majority of cartridges available, past and present.… Read more
