CAF 2018: The Conion C-100F Boombox Rocks the Washington D.C. Hilton Lobby

The Conion C-100F is a Japanese made Stereo 4-band FM/AM Tuner, Double Cassette Recorder Boombox. At nearly 30” wide, 16” tall, 8” deep and weighing 22lbs, this is a boombox of gargantuan size, with booming sonics, and dripping with deliciously gaudy ‘80s swag.

Produced in the early 1980’s by a sub-company of the Coney Onkyo Corporation of Japan, the C-100F has been seen on (or in) everything from album covers, to music videos, and more recently — clothing.… Read the full article

RMAF 2018: Jeff Rowland Design Group and the Ultimate Phono Pre for Multiple Tonearms

By | November 15th, 2018|Categories: Part-Time Audiofile|Tags: , , , , , , |

Lucien Pichette of the Jeff Rowland Design Group is an old friend of ours. He grew up in Montrose, Colorado, where Colleen and I lived for a few years, and I used to drive past his boyhood home nearly every day. I was happy to visit with him in the Rowland room at the 2018 Rocky Mountain Audio Fest and talk about Colorado, but I kept getting distracted by the beautiful shiny faceplates of the gear in the room.

If you’ve ever seen a Rowland product, you know exactly what I mean—even though this was just a static display of the current Rowland models, attendees were wandering in, mesmerized by these shimmering amplifiers and preamplifiers.… Read the full article

DIY All-Tube Phono Stage Project, Part 3: Metal Working For Dummies

DIY All-Tube Phono Preamp Project

Part 3, Metal-Working for Dummies

By Steve Graham, chief dummy

Working with fire and steel?  Would you believe alcohol and aluminum?  Bonus points to those who can name the 80’s pop group that issued the album shown above.  No cheating searching the title online.

Before we start torturing some metal: If you are sitting on the fence, wondering whether or not to build one of these for the following reasons:

  1. You think this preamp won’t have enough gain because it uses a 6DJ8 for the first stage (a 12AT7 is used for the second stage): Most line stages have plenty of gain so it takes some of the gain burden off of the phono stage.

VPI Player Review | The Millennial Audiophile

By | October 20th, 2018|Categories: Part-Time Audiofile|Tags: , , , , , , , , , , , , , |

ES000422

VPI re-imagines the turntable, and creates a new product category with the Player

When I speak about record collecting with the under thirty-five crowd, initially many of them see vinyl as a low-fi medium, much like cassette tapes, and 8-tracks. This impression was created by dusty hand-me-down turntables, and record collections of which most have unkempt and dirty grooves. Along with many of the new records purchased during the “2008 vinyl resurgence” being played on these un-serviced thrift-store turntables, many more will find their way to the affordable shopping-mall Crosley suitcase models.… Read the full article

Bits and pieces galore, but don’t worry, I’m a man with a plan

A quick note before we start.  As I write this, on September 28, 2018 my local hospital has today taken delivery of its new CAT scan machine for the diagnostic imaging department.  They were literally rolling it in the door today.Read the full article

Update: DIY All-Tube Phono Preamp Project / Part 1

By Steve Graham

Prototype shown above, the one I’m building for our kind patron will be similar but somewhat prettier

Thunderbirds are GO!

Hopefully International Rescue won’t need to be called.  (link)

I was a bit old for it when the Thunderbirds TV series arrived in the mid 1960s, but my two younger brothers enjoyed it. Now I find them charming, in that endearingly hokey way the Brits sometimes do things.… Read the full article

Its face may be a bit plain, but its heart is golden.

DIY All-Tube Phono Preamp Project (Update)

by Steve Graham

The response to my proposed DIY Phono Preamp project has been a bit tepid.  So, once more with feeling: WoS is looking for a patron to finance this project.  The kind person that fronts this project will, at the end of it, receive a phono stage very similar to the one pictured here.

The preamp pictured here (my prototype) uses a Tubecad Tetra phono amplifier board and PS-3 power supply.… Read the full article

Top Of The Line HiFi Gear From Yamaha Announced

By | August 25th, 2018|Categories: Wall of sound|Tags: , , , , , , , , , |

Well, well. First it was Technics, and now Yamaha….

Back in the 1970’s, Yamaha was a formidable player in the audio world. And ever since, really. The lower and mid-priced gear gained huge market acceptance. Some of their higher end electronics were made in partnership with Accuphase, while their top turntables like the GT-750 and GT-2000 were collaborations with Micro-Seiki. This TOTL stuff from the 70’s and 80’s is still sought after today. And the trickle down effect was pretty good too.… Read the full article
