Check out this beautiful Luxman M-4000 power amplifier I serviced recently. Let’s take a look at this classic vintage beast.

The Luxman M-4000 power amplifier is a fairly compact, dense, 180 Watt per channel bipolar design. It’s the predecessor to the M-4000A, which looks very similar, but is substantially different design-wise, and even rarer. I completely restored an M-4000A for a customer a couple of years ago.… Read more

Every so often, a customer brings me a piece of gear that reminds me how much I love vintage hi-fi. The Dual 1219 idler drive turntable is just such a piece.

Denon SL-7D Direct Drive Turntable Service & Review

This lovely Denon SL-7D direct drive turntable needed a thorough service in order to play records nicely again. I figured it was a great opportunity to review this classic deck.

Accuphase P-600 Monster Stereo Power Amplifier Voltage Conversion

Holy balls, the Accuphase P-600 Stereo Power Amplifier is one B-I-G mother of an amplifier. It actually gets physically tiring moving these beasts around the workshop!

Anyway, I’m not complaining, I LOVE working on equipment like this, even if it is heavy and the work slow. The Accuphase P-600 was, as far as I recall, Accuphase’s best class A/B stereo power amplifier back around the early 80’s.… Read more
