A Listening Adventure: A Trio of Modified Vintage McIntosh MX110 Tuner-Preamplifiers

Ron, Leo, and I got together last weekend to listen to a trio of vintage McIntosh MX110s variously modified by Ron-san with Real Sound modifications as suggested by Yazaki-san, which are similar to the modifications Yazaki-san has performed on his personal vintage Marantz 7 preamplifier. Prior to being modified by Ron-san, two of the MX110s were restored – mine and George’s – by the vintage McIntosh team of Tom Manley & Terry DeWick at McIntosh Home Audio & DeWick Repairs. […]

The Duelund CAST Hybrid Silver-Copper Capacitors Adventure

I wanted to tell you a little more about the new 6.8uF Duelund CAST hybrid silver-copper capacitors from Frederik that I mentioned in this post. As a refresher, let me remind you how the hand-crafted Duelund CAST silver & copper capacitors are made. In the Duelund CAST capacitors Frederik uses only pure annealed soft copper or silver foil in natural paper and oil, along with resonance control both inside and outside the capacitor. A capacitor […]

Gary Fischer’s A5 ‘Voice of the Theatre’ Restoration Part 3: the 288C, 1005B, and 515B

In my Part 1 post I introduced you to Gary Fischer and the Altec-Lansing A5 Voice of the Theatre restoration he did for me that forms the basis of the Altec A5 VOTT Project here at Jeff’s Place. For my restoration, I chose two 825B bass horn cabinets, two 515B Alnico low-frequency drivers, two N-500-C crossovers, two 1005B 10-cell horns, and two 288C Alnico high-frequency compression drivers, which is a classic Altec-Lansing A5 Voice of the Theatre combination of components from that period, […]

The Westminster Royal SE Duelund CAST Crossover Project: Hybrid Silver-Copper CAST Capacitors

I’m on a crossover roll to start off 2016, and now it’s time to discuss some exciting developments with the Duelund CAST crossovers that form the beating heart of my Tannoy Westminster Royal SE loudspeakers. In the The Duelund Coherent Audio / Tannoy Westminster Royal Special Edition Project that I chronicled in real time here at Jeff’s Place, ultimately writing up as feature articles for Positive Feedback (Part 1 – Issue 70; Part 2 – Issue 74), the pair […]

The Jeff Awards for 2015 ¸¸.•*¨*•♫♪ Ron Barbee ¸¸.•*¨*•♫♪

As I was preparing the Jeff Award for Yazaki-san, I was also thinking about another friend who has had a profound influence on me and my enjoyment of the audio & musical arts over the last several years, my good friend and fellow audio adventurer, Ron Barbee. Ron is a life-long audio enthusiast, music lover, musician (guitarist), and has the highly trained mind of an engineer – he is a true modern day renaissance man. Ron-san – like […]

The Jeff Awards for 2015 ¸¸.•*¨*•♫♪ Shirokazu Yazaki ¸¸.•*¨*•♫♪

For my 12th Annual Positive Feedback Writers’ Choice Awards I did something that I’ve never done before, I gave an award to a person instead of an audio product, Mr. Shirokazu Yazaki. The Positive Feedback Writer’s Choice Award acknowledges Mr. Shirokazu Yazaki for “his significant design work” which he surely deserves. In Japan, the term ‘Living National Treasure’ refers to those individuals who are designated as keepers of important dramatic, musical, artistic, and other intangible, high value, cultural […]

Gary Fischer’s A5 ‘Voice of the Theatre’ Restoration Part 2: The Bass Horn Cabinets

As I promised in my Part 1 blog post, using the A5 VOTT loudspeaker system that Gary Fischer restored for me as an example (below), I’ll describe the details of Gary’s restoration process. One thing that I really appreciated was that Gary sent me photos and kept me informed about what he was doing as the restoration proceeded, which really gave me a greater understanding of the A5 Voice of the Theatre loudspeaker system, and […]

I’m really impressed with the quality of Gary Fischer’s restoration of the Altec-Lansing A5 Voice of the Theatre (VOTT) loudspeakers that I purchased from him, so I wanted to tell you a little bit more about Gary and his restorations. To serve as the basis of my A5 VOTT Project here at Jeff’s Place, I wanted to get a pair of vintage Altec A5 VOTTs that were as original & pristine as possible, and Gary Fischer did a beautiful job of […]
