OJAS @ Lisson Gallery NYC

Our dear friends Charito and Joey, whom we haven't seen for over five years, were in NYC visiting for a couple of days. On short notice, Tish was able to take a day off so we were able to meet up with them. Joey is an avid audio DIYer and was a frequent collaborator especially during the annual November Hifi Show when I was still based in Manila. He represents G.I.P. Laboratory in the Philippines. 

It was also timely that Devon (OJAS) Turnbull's HiFi Dream Listening Room No. 1 exhibit at the Lisson Gallery NYC was on its penultimate week. So Joey and I agreed that this was going to be our meeting place! 

The OJAS loudspeaker system utilizes Great Plains Audio drivers, which are currently produced using original Altec tooling - GPA 416B 16" woofers + GPA 288H 1.4" compression drivers. The latter compression drivers are coupled to bespoke OJAS 1505 horns, which are remastered versions of the classic Altec 1505B multi-cells, while Pioneer PTR9 ribbon super tweeters fill-in the top-end octave harmonic overtones. At the center is a Fostex FW800HS super woofer. Devon starts with Werner Jagusch crossovers but driver loading and alignment are all developed in-house and then fine tuned by ear!

Having spent almost a decade studying at The Juilliard School twenty years before the Diller Scofido + Renfro reboot, I developed an immediate affinity for the brutalist vibe of the speakers!

The OJAS gestalt brought back cherished memories of the late Don Garber's Fi audio gallery from the early 90s, which was along 30 Watts Street in SoHo NYC. I wasn't able to ask Devon if he got the chance to meet Don. I bet they would have gotten along really well!

A pair of Altec/Peerless 4722 SUTs are mounted directly on a FET-based phono preamp using vacuum tubes as constant current sources. This was designed by jazz guitarist Steve Berger, who's also the man behind Aprilsound NYC. The adjacent chassis with two large knobs houses a transformer volume control wound by Dave Slagle of Intact Audio.

Being a devoted Garrard 301 listener for many years, Devon is cognizant of the finite supply of these idler driven classics. So for this project, he chose the platter + motor from a Technics SL1200G and mounted them in a custom layered plywood plinth. To assure absolute speed stability and smoothness in operation, a 3-speed linear power supply was specially designed by Linear Tube Audio. Having done DJ work during his younger years, he admits that his choice was partially in reverence to the marque.

Mounted at the back is an Ortofon RMA309 tonearm + a restored vintage SPU-A for stereo LPs and a Dynavector DV505 tonearm + SPU mono CG 65 Di for 78 rpm shellac discs.

Devon's pair of SE300B mono-blocks (fitted with Tango XE20S output transformers) is an homage - not a slavish copy but his own interpretation - to Herb Reichert's Flesh and Blood amplifier published in Sound Practices Issue 8. 

Unlike a typical hi-fi show swarming with silver-haired or balding guys, it was refreshing to be surrounded by a twenty-to-forty something crowd. Devon is attracting and developing a niche market uncharted by mainstream high-end audio publications such as Stereophile and The Absolute Sound. Due to his background in design and interaction with the upper echelons of the fashion and music industries, the whole Sound Practices ethos of music reproduction spearheaded in the early 1990s by Joe Roberts will hopefully reach a larger audience. 

Joey and I spent a couple of hours listening to Blue Note jazz, contemporary classical music, and talking shop with Devon. He was a very gracious host, who candidly gave credit to his collaborators as well as to those people who've influenced and inspired him.

Me, Devon, and Joey

Bravo, Devon, very well done! 

After several years of PMs, it was great to finally meet you. I look forward to more shop talk when you visit my man cave.

Devon's HiFi Dream Listening Room No. 1 exhibit at the Lisson Gallery in Chelsea NYC is really worth hearing and seeing! 

Open Monday - Friday from 11am - 6pm until August 5, 2022.

This 'zine contains comprehensive information about the whole hifi installation + more!

Factory Records Shop Dover NJ

Every time Tish and I go on a long drive, I'm always on the lookout for antique malls, flea markets and record stores along the way. On this particular weekend, we were en route to visit friends in Rye, NY. 

 

To avoid the monotony of New Jersey turnpike and congestion on George Washington Bridge, I took the longer route through scenic back roads of PA via New Hope to catch Route 202 and I-287. Then I exited for a brief detour to Dover NJ to check out Factory Records.

Rows and rows of Rock, Pop, Metal, Jazz, etc. of new and used LPs! Some CDs, DVDs and VHS tapes as well.

I'm a sucker for the warehouse vibe!

What use are LPs without record players...

...amplifiers and speakers?

It was a pleasant stop over!

I picked up these three 80s LPs for a very reasonable amount!

Stop by if you're in the area!

The following two pictures were taken by my navigator and co-pilot. 😊

SRPP SE2A3 Circuit Redux

Back in the late 90s, I dismissed the hi-mu/low-gm SRPP input/driver because I found that the circuit had a tendency to sound tiring over extended listening. However, my memorable encounter with the Morikawa SE2A3 amp owned by my buddy Jose was haunting. I had to revisit this circuit just to make sure I left no stones unturned. 

Earlier this year, Steve of Angela Instruments shipped me the "shop mule" SRPP SE2A3 amp for a check up. After replacing the leaky coupling caps, the amp was as good as when I delivered it to the shop over two decades ago.  

My hotter operating point = slightly more power compared to Prof. Morikawa's SRPP 2A3 amp.

!!!WARNING!!! 

The voltages in this circuit are potentially lethal! Build at your own risk!

In spite of the 10 kHz square wave spike from the budget Hammond 125ESE output transformers, it was a very refreshing musical reunion with the Angela SRPP 2A3 amp. 

During its residency in the man cave, the amp powered my back up Altec 2-way system above, Altec 755As and Altec 755Cs in Silbatone cabs below. It was totally devoid of the listener fatigue I previously ascribed to the circuit. Even with the brightest and harshest software and/or hardware thrown into the listening chain, I couldn't induce the unpleasant quality which bothered me in the past. 

Then it dawned on me that I started doubting the SRPP's musical abilities when my Altec 2-way project commenced. Sorry SRPP, it wasn't your fault...😟

YMMV!😉

Hub City Vinyl

We took a long drive to visit relatives in Western Maryland for Memorial Day weekend.

I made sure we checked out Hub City Vinyl in downtown Hagerstown, MD. This really cool record store is housed in an Art Deco structure that served as a car dealership in its previous life.

I was based here from the latter part of the 90s till the late 2000s and never imagined a well-stocked record store of this size could thrive in this town.

Notice da boss patiently waiting in the listening lounge?

The Zu Omen speakers driven by Schiit Audio electronics with Steely Dan's "Gaucho" spinning on a Technics turntable made the atmosphere even more endearing!

Towards the back of the building is another room full of LPs and CDs.

The left hand corner of that room had stacks of classic hifi gear!

 This Gates CB1200 3-speed idler driven turntable + Gray 206 viscous damped tonearm definitely caught my eye. But I've run out of space and need to unload to pacify the boss.😉 

So I hope a blog reader will buy the above set up and enjoy it!🍻

I like the black out aesthetics of this 70s Plainview NY era Harman Kardon 330C receiver, which sported technically innovative circuitry. The rack mountable Tandberg tuner is also interesting!

How about a custom tube amp using 6BL7 tubes?

One of the sales associates told me that the back end of the building will eventually be transformed into a live music venue as the pandemic winds down. This is really great news for the cultural life of Washington County!

If you're a record collector and/or audio buff driving through the junction of I-81 and I-70, this place is a must-see!

Welcome, summer! Safe travels!

Fidelity Research FR64fx - dead channel fix

After many years of service, my FR64fx tonearm dropped one channel. 

I started sleuthing by studying the vertical pillar.

By peeling off the tonearm height scale (essentially an aluminum backed sticker), the set screws are exposed.

I loosened the set screws to carefully pull out the 5-pin DIN terminal + horizontal bearing housing from the vertical pillar. The unsoldered wire was instantly visible. 

After soldering the broken connection, I re-assembled in reverse order. I used rubber cement to secure the tonearm height scale back to the groove in the vertical pillar. 

Happy listening!

Kutztown Radio Show Spring 2022

All pictures taken with a Fuji X-E3 camera + W-Nikkor 35mm f2.5 LTM lens

It's hamfest and radio show season!👏

 

On Friday, May 13th, I drove through the back roads northwest of Philly towards Kutztown with Ding, who attended this event for the first time.

The weather wasn't very cooperative. Soon after we got there, this vendor had to move to the pavilion due to a heavy downpour.

There weren't as many vacuum tubes compared to the past years, but Ding found enough 5U4Gs to replenish is stash.

A pair of Utah Celeste 12" co-axials driven by a DIY 6CK4 SE amps in para-feed mode provided nice tunes.

I've never been a JBL fan, but here's a pair of 4311B monitors + a Harman Kardon receiver.

Green Altec 802D + 806A!👍 

Unfortunately, the diaphragms were fried.😥

Hifi guys

A nice monophonic hifi system could be built around this University 6201 co-ax housed in a nice mid-century modern cabinet!

A pair of Heathkit W-7 PP EL34 monoblocks + a DIY tube amp

When stuff I used to see at Circuit City, Crazy Eddie, J&R Music World, The Wiz, etc. are considered vintage, we can only guess what that means.😆

Technics SP15 + a mixing console and a cool art deco TV

Before leaving, I spotted this '56 Chevy Bel-Air.

My paternal grandparents had one, albeit, black and white, 235 cid "blue flame" straight six + three on the tree. It was in service until 1981. 

See you in September!
