🎄Happy Holidays to everyone!🎄
In late 2023, Serge Rogozyansky of Karmadon posted his exquisitely crafted Ortofon-inspired 12" tonearm on Facebook. Being an aficionado of bespoked pieces, I was smitten! When I mentioned it to Tish, her immediate reaction was, "You already have too many turntables and tonearms!"😉
Due to an upcoming visit to the Philippines, I had to curb my enthusiasm.
I ordered the Intact Audio speaker autoformer with a -6dB to -15.5 dB/0.5dB attenuation range based on the fact that my Altec 802 drivers are about 12dB more sensitive than my 99 dB/1W/1M Altec 414A woofers. Other than that, I went into this project hoping that Google would be my friend, only to find out it wasn't!😉
Since I use external crossovers for my Altec 753C, disconnecting (and reconnecting for comparison purposes) the Altec 32C/802 horn/compression driver is a breeze. The 753C-style cabinets essentially serve as bass bins in which the 414A woofers operating in wide range mode (unfiltered) + the 20275 diaphragmed 802 compression drivers mounted on the Lycan3R WP12024 horns are perched on top!

This past weekend, Tish and I attended a wonderful celebration of my dear friend Steve Melkisethian's life (1950-2024)!
Over two decades ago, I ventured into single channel music reproduction to trace the roots of high fidelity. From that whole experience, I developed an aesthetic quest for a certain purity and honesty in sound, which runs parallel with my other hobby of black and white film photography! Sadly, I had to leave that particular mono set up in the attic in 2017.
This ca. 1969 Kenwood turntable adapted the Thorens TD124 drive system sans eddy current speed control.
Whenever I find them at reasonable prices, I re-acquire audio components I owned and enjoyed in the 80s. I started my quest with the Grace G707 tonearm, a TDA1541-equipped Magnavox CDB 473 CD player and the dynakit stereo 35 PP EL84 power amp. I also tried to rekindle my affection for the BBC LS3/5A monitor and my MC SUT collection now includes a pair of Sony HA-T10s. Meanwhile, I've been hunting for an AR XA turntable and a first generation NAD 3020 to complete my journey back in time.
During a recent visit to Steve and Ray at VAS Audio, my attention was caught by an amplifier I built in the early 2000s. This is one of the very few I released into the wild.

Whether it's an open baffle as conceived by G.A. Briggs or an enclosed box like the Western Electric utility boxes above, I've always been an advocate for a wide baffle design. The wide frontal area serves as an acoustic reflector that helps propagate sound toward the listener instead of escaping to the sides and back. Somehow the wide baffle, whether open or closed, always makes reproduced music sound more alive to my ears!
A notable exception is the narrow front baffle Silbatone box designed by Dr. Stefano Bae for the Western Electric/Altec 755A. Since I uploaded the cabinet project under the auspices of Joe Roberts, it has garnered a following amongst DIYers who've reported successful results mounting other 8' drivers like the Altec 755C, 755E and the Lafayette SK98/Pioneer PIM8L.
I finally got a chance to mount and listen to my 755Cs and PIM8Ls + other 8" wide band drivers. Hopefully, this article will encourage readers to DIY this mini-monitor sized box because it really offers a lot of musical pleasure per cubic inch!
To recap, let's start with the...
At the dawn of the 21st century, I uploaded hifi systems owned by audio buddies who had been inspired by the Sound Practices ethos. These were the guys who originally coined SETUP. After a couple of decades, the number of Filipinos who indulge in this hobby has increased exponentially.
Here's what I saw and heard during my recent visit.😊
Just like cars, a new turntable model has to be introduced every year or two to keep consumers' interest and convince them that newer is better.😊

The Realistic Mark 8 improved upon the similar looking "motor unit-stye" Mark 7 in Part 4 of this series by adding a 16 rpm speed and supplying a half pound heavier cast aluminum platter.
During my visit to the OJAS listening room late last year, Devon asked me to evaluate a pair of horns OJAS developed in collaboration with Lycan R&R. The OJAS 529B is a 500 Hz horn rescaled from the large format Altec 329A for use with 1" format Altec/GPA compression drivers.
My dad would've turned 97 today. To celebrate his birthday, the video clip above features a recording of his favorite violinist, Nathan Milstein, playing Presto from Bach's Sonata No. 1 in G minor for unaccompanied violin. While he was doing post-graduate studies at The Juilliard School in the mid 50s, he was fortunate to have attended concerts of the great violin virtuosos of that era - Jascha Heifetz, David Oistrakh, Nathan Milstein, etc.
He would later recount that Nathan Milstein's performance of the Glazunov violin concerto was the most unforgettable! Even if he never got a chance to add this violin concerto to his repertoire, he conducted the Manila Chamber Orchestra with me playing the Glazunov violin concerto in 1987. The music of the slide clip above is the middle movement from our performance.
Before I bore everyone reminiscing about my dad and our life as musicians, let's get on with the subject at hand. The amp featured in this upload uses a directly heated triode power tube that was introduced around the time my dad was born.

While browsing at Books Kinokuniya in NYC in the 90's, this Noguchi ad from the November 1994 MJ Audio Technology issue inspired me to experiment with line transformers as digital sound enhancers. Since I was living on a post-grad assistantship budget back then, importing this pair from Japan was out of the question.
