Dual 1219 Idler Drive Turntable Major Service & Repair

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.

The Dual 1219 idler drive turntable is a relic from an era when almost everything was made out of metal and wood. The deck is German, and old, so this type of solid construction should be no surprise.… Read more

Accuphase C-202 Line-Level Preamplifier Service & Review

The Accuphase C-202 line-level class-A preamplifier is an extraordinary piece of hi-fi gear. Come with me as I review and service this amazing preamp.

The Accuphase C-202 is a line-level, class-A, fully balanced preamplifier, with dedicated CD buffer circuit. By any measure, it is a superb piece of gear. It’s not one of Accuphase’s best known pieces however, good news if you decide to buy one.… Read more

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.

I’ve written about the Denon SL-7D previously, they are good, honest turntables and I enjoy working on them. The SL-7D definitely isn’t a super-deck, but they are well-engineered turntables, relatively affordable and, with regular service, should provide many years of listening pleasure.… Read more

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 bloody heavy. 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

Yamaha CX-1 Preamplifier Service & Repair

You may have seen the article I wrote recently about repairing a gorgeous Yamaha MX-1 power amplifier. This time I’m servicing a Yamaha CX-1 preamplifier, which matches the MX-1 and is part of the same set.

Yamaha made some really superb hi-fi gear back in the day, as I’m sure many of you know. There were the B series VFET amps like the B-1 and B-2, the legendary NS-1000 monitor loudspeakers, the perhaps even more (studio) famous NS-10 monitors, awesome MX-10000, CX-10000, and many more.… Read more
