Grandma Jaine is 91 now, soon to be 92, and loves jazz and Robert Redford movies! Grandma Jaine is Chris' Grandmother... Read More »


A Sunday Afternoon At Place de Jeff: Altec, Duelund, Yamamoto, and R2R! Update x 2.


It's always fun to get together with good friends, and I was delighted to have pals Leo, Pete, Ron, and Santos visit me for a frivolous Sunday afternoon of laughter, music, and hi-fi tomfoolery at Jeff's Place!

Duelund DCA16GA on the Altec 16 Ohm 515B Alnico drivers in the 825B bass horns, and now with a little 1005B 10-cell horns & 288C Alnico high-frequency compression drivers action thrown in.


After writing my last post, I got all excited about wiring up my A5 VOTT's Altec 16 Ohm 515B Alnico drivers in the 825B bass horns with Duelund DCA16GA wire. First I removed the backs of the Altec 825B bass horns so I could get at the 16 Ohm 515B Alnico drivers, and then removed the vintage... Read More »


Jeff checking in ... Duelund DCA16GA, 'Vintage Tone', and other stuff! Updates.


It's always good to get home and fire up the stereo after being off on a long week of work travel. The first thing I did after getting home from a long day of flying was to plug in my vintage McIntosh vacuum tube electronics and vintage Altec A5 Voice of the Theatre loudspeakers based system to...

Jeff checking in ... 2 tips, DCA16GA update, Bumblebees & Red Astrons, and the A5 VOTTs!


It's been a crazy busy time for yours truly, with travel, work, looking after my 91-year young Mom, getting ready for some memorial services for my Dad, keeping up here at Jeff's Place, and the like. Sometimes 24 hours in a day seems woefully insufficient. But I wanted to check in and say, "Hi!" and... Read More »


Frederik Carøe DCA16GA update x 2!


I've been traveling in England the last couple weeks and got home last night at 1 a.m., and am now trying to get caught back up on everything, including some sleep and some music listening. I was on a tour with Rick Steves' Europe that was a lot of fun. Rick is a cultural treasure... Read More »


The Jupiter Condenser 'Red Astron' Capacitors in the MX110Z!


I had intended to spend quite a lot more time listening to the gorgeous sounding vintage Sprague Bumblebee 0.22uF capacitors in the C93 & C95 and C94 & C96 positions of my MX110Z to establish a 'baseline' before trying any more capacitors. The Bumblebee's are my favorites of all the capacitors I've tried in those positions for the MX110Z... Read More »


Today's Fresh Catch: Red "Astron" Style Capacitors from Jupiter Condenser


I have really been having a lot of fun listening to various capacitors in my vintage McIntosh MX110Z tuner-preamplifier.

The half a century old Bumblebees have... Read More »

The Vintage McIntosh MX110Z Adventure Meets Vintage Sprague Bumblebees!


After getting up this fine Saturday morning, while drinking a couple cups of my favorite coffee from Stumptown Coffee Roasters, I set about pulling off the bottom of my vintage vacuum tube McIntosh MX110Z tuner-preamplifier so I could do a little surgery on it. I had two things I wanted to do while under the bonnet, the... Read More »


Today's Fresh Catch: Bumblebees & Tropical Fish


If you read my recent post about tone capacitors you know there are three vintage capacitors that are very highly regarded for their tone, the Sprague Black Beauty, the Sprague Bumblebee, and the Mullard Tropical Fish, and they represent a sort of 'holy trinity' of tone for electric guitarists, as well as being at least partly responsible for the rich, musical tone,...

Markus Klug's 'Klughoerner' hand-crafted wood replicas of historic Altec multi-cell horns! (updated with more photos)


I'm not often gobsmacked by audio gear anymore, but when I laid my eyes on Markus Klug's Klughoerner hand-crafted wood replicas of historic multi-cell horns I almost swooned and fell out of my chair! Markus' Klughoerner multi-cell wood horns are stunning! To the right in the photo above, you can see Markus' hand-crafted Klughoerner wood replica... Read More »


The Altec A5 Voice of the Theatre project progresses ... and other stuff! (now with more updates)


I had a nice day of music listening yesterday afternoon with Leo, Pete, and Ron, as we did some listening comparisons with the Altec A5 Voice of the Theatre loudspeakers and their Hiraga-san inspired crossovers. The Jean Hiraga designed crossovers are about as perfect a match to the Altec A5 Voice of the Theatre loudspeakers as one could hope for,... Read More »


Breaking news! Duelund Coherent Audio DCA16GA! I'm really excited about this! Update!


A lot of you (and me) have been lamenting that the superb Western Electric WE16GA wire has become essentially extinct, and I am down to the last little bit of WE16GA I have left, which is what I am using to wire my new crossovers for my Altec A5 Voice of the Theatre loudspeakers project....

A Couple of Breadboards for the Altec A5 VOTT Project!


As I have gotten older I've found myself becoming more interested in history in general, and our audio history in particular. Over the last ten or fifteen years I've become increasingly fascinated with the vintage Altec Lansing Voice of the Theatre loudspeakers that started their storied journey into theaters back in 1945, as World War II was winding to...

The A5 VOTT Project Commences: Resistors and capacitors, and inductors, oh my!


I am delighted to say that the vintage Altec-Lansing A5 Voice of the Theatre Project is now moving forward again! In the first phase of the project I commissioned Gary Fischer to restore a vintage pair of Altec-Lansing A5 Voice of the Theatre loudspeakers, which I described in three parts: Part 1, Part 2, and Part 3....

The Vintage McIntosh Resistor Adventure Continues (and other stuff)!


While doing the vintage McIntosh MX110 tuner-preamplifier adventure we experimented with several brands of new & NOS metal film resistors in the circuit in various places, but basically I always ended up preferring the vintage 2-watt NOS Allen Bradley carbon comp resistors that Andy Moore had suggested I try. The vintage 2-watt NOS Allen Bradley resistors had better tone,... Read More »


Jeff checking in ... a look into the crystal ball: the past, present, and future!


The Vintage Beat It sure has been a wonderful experience dipping my toe into the waters of vintage hi-fi gear, like with my original Garrard Project (1, 2, 3) articles: Or with my restored vintage McIntosh kit like the MX110Z tuner-preamplifier, stereo MC240 amplifier, stereo MC225 amplifier, and MC30 monaural amplifiers: Or the world of vintage...

Ron-san and I got together today to celebrate the joys of audio & music and to listen to the latest iteration of our Real Sound Adventure with the vintage McIntosh MX110 tuner-preamplifiers.

The Vintage McIntosh MX110 Tuner-Preamplifier Adventure: The Tepro Transformation!


Have you ever woken up in the middle of the night with a major revelation? In my case my major revelation came at 2:53 a.m. last night, according to the screen on my iPhone. It was three thoughts coming together that triggered my overall revelation, but I want to tell you the story in the sequence that it occurred... Read More »

I was so pleased with my vintage McIntosh MX110 tuner-preamplifier 'resistor adventure' this morning I just had to tell you about it!
