AnalogPlanet Visits Optical Cartridge Manufacturer DS Audio Analog Planet
Published on Oct 3, 2017
After the Tokyo International Audio Show 2017 and just before heading for the airport to go home, AnalogPlanet editor Michael Fremer visited two Japanese cartridge manufacturers. The first one was DS Audio, located in the Sagami-Ono, Kanagawa Prefecture about an hour from Tokyo.
The company, founded by Mr. Tetsuji Aoyagi, has a long, distinguished heritage beginning with the invention of the optical mouse and the joystick both co-developed with Microsoft.
Mr. Aoyagi's young son Tetsuaki (Aki) overseas the development and marketing of the company's series of optical cartridges. In this video Aki explains how that happened and a great deal more.

(Note: this video was revised 10/7/17 at the request of a company for which Excel OEMs). Just before heading to Tokyo's Narita airport to go home, AnalogPlanet.com editor Michael Fremer stopped by at Excel Sound Corporation in Yokohama, which manufactures Hana brand cartridges as well as OEM-ing for many other brands.
He was met at the front door by publicist and president of Youtek Limited Hiroshi Ishihara and Excel Sound Corporation president Masao Okada.
As you'll see and hear during the tour of the facility, there were frequent translation issues that led to some humorous and/or frustrating communications.
Still, there was much to see and learn about a company that managed to survive the "death of vinyl" by expanding into low priced accessories until the near miraculous resurgence of interest in vinyl records

K-Tel took the already short single edit of "Layla" and faded it out 15 seconds early, to help squeeze 22 songs onto one LP. This version of the song hit #51 on the Billboard Hot 100 chart in 1971. The following year, the full-length album version became a #10 hit.

From one of the last Living Strings albums released before RCA discontinued their "Living Series" in 1981. The RCA Music Service record label surely means it was only available through mail order. The last gasp of traditional instrumental Easy Listening music, before it got replaced by New Age and Smooth Jazz.

Are there any good cheap vinyl records left? VWestlife

Yes, especially now that "alternative" music of the past has become mainstream among vinyl collectors, for a bargain price you can be prepared for the mainstream music of the past to become the new alternative music that is considered "edgy" and counterculture (club) to listen to...
CX Discs : Better, Worse & the Same as a normal record - A Forgotten Format Techmoan
Published on Oct 19, 2017
CBS envisioned all records made after 1982 utilising their CX encoding system, but if you've bought any music on vinyl since the mid 80s, you won't see a CX logo on the sleeve...so what was CX and what went wrong. Watch this video to find out.
Q) if you could have played the audio samples shown, what do they sound like
A) It’s very hard to spot the differences. It’s just that the very quietest moments (which are fleeting and only last for a fraction of a second in these pop songs) are a little bit louder. You can hear the section highlighted on the waveform in the link below -and you'll see why I didn't include it in the video as it does a very good job of proving very little. The sample is played in the following order CX Disc, CX=ON, Normal Record, CX Disc, CX=OFF http://bit.ly/2yYG36M
Q) Did CED & LaserDisc players have built in CX decoders
A) Yes they did..except for some of the very earliest models.
Q) Could you take pictures of both sides of that circuit so I can try and reverse engineer it and make my own CX decoder.
A) Nope - there's no need - Instead, follow the guide in this issue of Popular Electronics if you want to build your own http://www.americanradiohistory.com/A...
Using a Digital Microscope to Set Stylus Rake Angle Analog Planet
Published on Oct 23, 2017
This video shows you how to use a digital USB microscope to set stylus rake angle (SRA) to 92 degrees, which is considered to be the best angle to start with, followed by adjusting "by ear". Why 92 degrees? It's all explained in an article you can download as a PDF file at this analogPlanet.com link: https://www.analogplanet.com/content/...
Short explanation: when records are cut the thread of just cut lacquer is extremely volatile and must be vacuumed into a collection jar. The thread must be removed from behind the cutter head, so the cutting stylus angle must make an angle of more than 90 degrees to the record surface in order to be extracted.
As you'll read in the analogPlanet story and in the PDF file, the authors traveled throughout America visiting mastering houses and measuring the cutter head stylus rake angles, which varied between 91 and about 94 or so degrees.
They chose 92 as an ideal compromise. However, if you wish to tweak it for every record in your collection, knock yourself out! I find 92 degrees suffices for most records. As for why this matters, you'll also find the answers in the analogPlanet post and the measurements in the PDF, which also includes a very interesting and useful discussion of various stylus profiles and their effect on sound.
