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

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

One look at a 6300 and you’ll reach an inevitable conclusion – that you want and need to find one to add to your collection.… Read more
