A Guest Article from Mr. Shirokazu Yazaki: “My Adventure With My Old Marantz Model 7” Part 7.


I am delighted to be able to share with you Part 7 of Yazaki-san's adventure with his vintage Marantz Model 7K preamplifier! I always enjoy reading what Yazaki-san has written, and I always learn a lot from his many insights. I would like to say a very special "Thank you!" to Yazaki-san for taking time... Read More »


Jeff checking in ...


After a couple cups of coffee this morning, I sat down and practiced my fingerstyle guitar lesson for about an hour. I'm enjoying working my way through a beginning fingerstyle guitar course book, in hopes that I'll become a better guitar player (it wouldn't take much! 😉 ). One of my goals in retirement has...

GE 6L6GC vs. Tung-Sol 6L6GC STR: The Day the Music Died!


I decided to bite the bullet and order two matched pairs of the increasingly rare & expensive NOS GE 6L6GC's for my vintage MC30 monaural amps, so I could compare the fresh new GE's to the new production Tung-Sol 6L6GC STR's. I have found certain aspects of the Tung-Sol's musical & sonic performance to be... Read More »


Tung-Sol 6L6GC-STR Vacuum Tubes. Update.


My favorite power tube for my vintage McIntosh MC30 monaural amplifiers have been the gray plate GE 6L6GC's. The GE's provided a warm, rich, and naturally musical presentation that even the highly esteemed black plate RCA 6L6GC's had to bow down to. For my hot-rodded MC30's the GE's take musicality to another level, but they... Read More »


Jeff checking in ... previews of coming attractions and other stuff!


This last week was really a nice one of relaxation and getting out in nature with my friend Chad at his cabin on the shore of Lake Chelan in Washington State. We got in a bike ride in the village of Chelan, and did some sightseeing around the lake. There were deer everywhere, and at... Read More »


Jeff checking in ... the hifi witching hour!


Have you ever had one of those periods of time where everything goes wrong? I'm in one of those periods now. Usually it seems like things go astray in triplets, for same strange reason. Usually, I sigh with relief after the third mishap, because things are about to get better, but this time it appears... Read More »


Duelund DCA wiring fun with Tannoy's and Altec's! Update.


As I've mentioned in previous posts, I've been having fun trying different wiring schemes with my Tannoy Westminster Royal SE loudspeakers and their Duelund CAST crossovers, as well as my vintage Altec based systems. Tannoy Westminster Royal SE based system: My living room music system is composed of Tannoy Westminster Royal SE loudspeakers with outboard... Read More »

It's been a nice weekend of just kicking back, relaxing, and celebrating. To celebrate my Mom's majority Irish ancestry that we didn't know she had until after some recent DNA testing (oral tradition isn't always accurate), we celebrated St. Patrick's Day on Saturday with me cooking a traditional St. Patrick's Day feast of corned beef,...

Almarro A205A EL84 Integrated Amplifier Duelund Coupling Cap Mod. Update x 2.


I've been using the sweet little Almarro A205A EL84 integrated amplifier to power my vintage Altec 832A Corona loudspeakers that I'm using in my bedroom system, and it's a really nice match for them. The volume pot has been kind of noisy in the A205A so I thought I'd pop the bottom off and squirt... Read More »


A Duelund DCA12GA tinned-copper wire adventure to kick off the weekend!


Remember my Big Round Tone post from a couple of weeks back, where I discussed the relationship of tone to gauge size for headshell leads, interconnects, speaker cables, and speaker/equipment internal wiring? In relative terms, you get bigger, richer, and rounder tone as gauge size decreases (fatter wire). You can think of it in guitar terms too.... Read More »


Kramer's Best Antique Improver


If you're like me, you've had a hard time finding finding a quality wood cleaner, restorer, and preserver, that doesn't contain things you don't want on fine or vintage wood finishes (i.e. silicone), or that leaves a waxy buildup that will oxidize to a dull finish over time. I've found something I am really impressed... Read More »


A little music to usher in the weekend!


We're all in this great hobby together because we love listening to and learning about music, and tinkering with our hifi gear. As hifi hobbyists it's easy to get so preoccupied with the hifi gear that we forget what attracted us to it to begin with, which is the pure pleasure of listening to music... Read More »


A Denon DL-103 phonograph cartridge-ectomy for Sunday!


In the last six decades I haven't broken a single phonograph cartridge, but in the last two weeks I've broken two, and the crazy thing about it is I don't even know how I did it in either case. The first cartridge fatality was the Audio MusiKraft Denon DL-103 phonograph cartridge Guy Pelletier sent me. I... Read More »


Voltage conditioning RCA adapters for the Hagerman FryBaby2 compact burn-in generator!


I really appreciate the emails I get from you. Take for example the recent email from Robert Atkinson, expanding upon using the Hagerman FryBaby2 compact burn-in generator for interconnects, speaker cables, capacitors, and resistors. Jim's manual for the FryBaby2 is very brief and doesn't really give the reader a comprehensive overview of the specifics of... Read More »


Big Round Tone


I've been looking at guitars again, or more exactly, vintage Gibson ES 150 guitars. YouTube example below. Listen to that incredible tone of "Fred Archtop's" 1938 Gibson ES 150 "Charlie Christian", it's out of this world! So what does that have to do with audio? Well, both guitars and audio intersect at music, that's what! You've heard... Read More »


Two jazz guitar LPs to ease you into the weekend!


I love jazz. I love guitars. I love to hear jazz cats playing jazz on their guitars! It makes me smile. 🙂 Blues Going Up is a nice jazz swing album featuring George Barnes (guitar), Duncan James (guitar), Benny Barth (drums), and Dean Reilly (bass), that was recorded live at Bimbo's "supper club" on April 17,...

A vinyl morning with the Altec A5 Voice of the Theatre loudspeakers!


To get my mind off the plunging stock market and my plunging retirement savings, I thought I'd do something edifying like give my Thorens TD124 a try on my vintage Altec A5 Voice of the Theatre loudspeakers. I've wanted to revisit the Leben CS-600 integrated amplifier and Leben RS-30EQ combination that works so well together... Read More »


Vintage Altec 832A Corona's as a bedroom system!


I went a bit wild today and decided to rearrange all my bedroom furniture so I could set up the new-to-me vintage Altec Corona loudspeakers as my bedroom system. The speakers look small in the photo above because of the size of the room, but they're really 3.5 feet tall and 3 feet wide, so... Read More »


Long-term report on the Spec RSA-M3 EX and Leben CS-600 integrated amplifiers!


I'm a huge fan of integrated amplifiers. In fact some of the finest amplification I've ever had the pleasure to listen to music with has come from integrated amplifiers, like the Leben CS-600 and the Spec RSA-M3 EX. I get quite a few messages from integrated amplifier owners asking me what separate components would better the... Read More »


The Pete Riggle Audio Engineering crossover project for vintage Altec domestic loudspeakers with 800Hz horns!


It turns out that with my purchase of a pair of vintage Altec 832A Corona loudspeakers, that there are now four of us local friends that have vintage Altec loudspeakers with 800Hz (811B) horns that were designed for domestic use (Valencia's, and now the Corona's). Altec built a lot of loudspeakers that were designed for... Read More »


Today's Fresh Catch: Vintage Altec Lansing 832A Corona loudspeakers!


The vintage Altec Lansing 832A Corona's arrived from LA Jazz Audio this morning via R+L Carriers, who were very helpful and polite, and brought the pallet with the Corona's right up to my front door for easy unpacking -great service! LA Jazz Audio did a nice packing job, and I was able to quickly remove... Read More »


A Sunday Afternoon on the Island of La Grande Jeffe ...


Today's post was inspired by Georges Seurat's A Sunday Afternoon on the Island of La Grande Jatte,  one of my favorite pointillist impressionism paintings, showing Parisians relaxing in a park on the banks of the Seine (below). In a silly oddio variation on a theme, you get my music, film, literature, and audio impressions while I'm relaxing... Read More »


Three guitarists on LP that you'll want to hear!


It's crazy, I thought I'd have 9 or 10 hours more every day to get things done after retiring from my day job at the end of December, but that hasn't happened. If anything I've been busier than ever and the days whiz by, and before I know it the day is over! How can... Read More »
