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

Luxman M-4000A Amplifier Restoration

The legendary Tim De Paravicini designed the original M-4000. The improved and even rarer Luxman M-4000A probably also came from De Paravicini’s hand, but nobody seems to know for sure.… Read more

Thorens TD-125 Turntable Repair & Restoration

I was at an old friend’s place recently, chatting to his father, who is very ill. Neil had always been a music lover and after chatting for a while, I saw that his cherished Thorens TD-125 Mark 2 was languishing, non-functional, in a pile of dust and dirt.
