In this video, I explain some considerations when correctly setting up a turntable like the Kenwood KD-600.
This particular deck came to me very poorly set-up. The deck’s owner received some very bad advice from, of all people, Ortofon! I’m a big fan of Ortofon gear, but clearly not everyone there knows what they are talking about.… Read more
Organising vinyl can be challenging at the best of times. If you’ve ever watched High Fidelity, and you should have, you’ll know that you can spend ages just working out how to categorise and sort your records. Before we get to that though, there is the age-old issue of how to store them…
Well, I’m happy to say that IKEA comes to the rescue once again, with a great range of storage solutions that suit records perfectly.… Read more
I decided to build a resistance standard, for use with my test and measurement gear and good enough that I could some calibration on test and measurement equipment owned by other people. I wanted to build something that would not be prohibitively expensive and that would allow me to reliably calibrate the resistance ranges of my two Keithley bench multimeters and various Fluke hand-held DMMs to at least 0.01% accuracy.… Read more
I’ve purchased some great new vinyl of late and recently took delivery of some great new polypropylene record sleeves. I get asked lots of questions about how I sleeve and house my records, so I figured I’d write an article about re-sleeving your record collection!
There are two main types of record outer sleeve: polyethylene and polypropylene.… Read more
I recently built a dual-mono LM3886 chip-amp / gainclone amplifier from a kit sold by Brian Bell, at chipamp.com. In this article, I discuss the history of the gainclone and how I built my first chip-amp!
The LM3886 is one of National Semiconductor’s single-chip monolithic amplifier integrated circuits. It’s almost an entire amplifier-on-a-chip, with only a few extra parts required to build a fully functional, high-performance amplifier.… Read more
I recently modified a Musical Fidelity X-CAN V3 headphone amplifier. My goal was to see what sort of improvements I could make without spending too much cash.
The X-CAN V3 uses bipolar output devices, with a tube driver stage. The tube driver stage is a JAN (Joint Army/Navy) 6922 mil-spec dual-triode tube, per channel. These tubes run in class-A and give the voltage gain necessary to drive a pair of BD139/BD140 bipolar transistors.… Read more
