Tomorrow morning: 7AM-9AM EST (that’s NYC time, buddy) I will be doing a guest DJ set on-air at WPKN, 89.5 FM.
If yr in the NYC metro area, you can tune in as you sit in traffic on I-95/the LIE/the Merritt/ etc.
Or just visit the WPKN website and click the ‘Listen Now’ button.
I ‘ve put together a set of electro and electro-pop from my LP stacks. All vinyl, folks. No cheating.
‘PKN is a wonderful listener-supported radio station that has been a big part of my musical life since I was a kid. Just some artists that I discovered via this venerable institution:

Above: The Fairchild Integrated Console of 1972
How y’all doing out there. Today at PS dot com: some interesting bits from the archive: a collection of Fairchild data sheets from 1972. Download all 12 pages here:
Products covered, with texts, specs, and photos, include: Fairchild ‘integrated’ console, Reverbertron 659A, the FPC series of ‘portable mixing consoles,’ 610 and 870 power amps, plus a whole slew of distribution amps and power supplies that i just ain’t got time to list. Enjoy!
Today on PS dot com: a 1971 article by one Robert C. Ehle on the subject of ‘The Electronic Music Studio.’
Download here: Elec_Music_1971
The article includes a schematic for an audio-triggered frequency divider (ala early ‘woodwind synthesizers’) and some interesting other bits, such as discussion of tape-based time compression (which we covered earlier,,, click here for that article).
Bleep Bleep.

How y’all doing out there in the land of Ooo… srry for the dearth of new ‘content’ lately; it’s been v v busy here at PS dot com HQ. Anyhow, I recently came across an interesting article in an old issue of DB magazine concerning distant-mic’ing. The authors are Roger Anderson and Robert Schulein; you can download it here:
DOWNLOAD: Distant_Micing
Essentially, the concept is that best-results with distant-mic’ing are obtained when the microphone is as close to the most prominent boundary (in most cases, the studio floor) as possible.
I use both a distant-mic and a close -mic on pretty much every instrument that I record at GCR; I don’t always use both sources, but shit, we’ve got a big, great-sounding room, why not record it? But I’ve always set the distant-mic on a stand approx. 4-feet above the floor, much like the diagram above. I carefully position it to obtain what I feel is an appropriate balance between direct and reflected sound, but I’ve never thought much about how far it is from the floor. Anderson & Schulein make a very compelling argument for doing otherwise, and I’m gonna give it a shot at this week’s sessions.
To all my working recording-engineer readers: thoughts on this technique? Weigh in,,,
,,,and today, perhaps unsurprisingly: some of the new kit unveiled in 1971 at the NYC AES show, also via DB mag. Of note: Auto-Tec, Scully, Ampex and 3M intro’d new 16-track machines, Neve made a push for a new console (would this have been the series 80?), AKG introduced the BX-20 reverb, Melcor showed its model 5001 electronic reverb (anyone???), and a new company called Eventide introduced a digital pitch-shift device! The Neumann U47-fet and Sennheiser MHK-815 mics were introduced, as were the Marantz 500 and Crown M2000 power amplifiers.

Boozhound Labs Phono Preamp Kit
I know. The grey box above ain’t much to look at in the abstract. But, it’s what’s inside the box that we are concerned with today. Jsn at Boozhound Labs (hf ‘BHL’) sent me one of his new “JFEt Phono Preamp Kits” to check out, and I’m glad I did. It was a quick+ easy project that has greatly improved my LP listening situation in the living room mini-system.
Above you can see the BHL preamp right beneath a little stereo power amp (with A/B input select and a stereo volume pot). The power amp is a design that I have built dozens of times for clients: a single 6SN7 is shared to provide one voltage-gain stage per channel, with each channel using a 6L6 (cathode biased) class-A to provide approx. 8 watts of power to each speaker. Just so you know where I’m coming from, here’s the complete setup: ADC QLM 30 mk III cartridge mounted on a Technics 1200 table, then into the BHL, then to the SE 8-watt power amp, and finally to JBL 18ti speakers. Very circa-1980. The other input of the power amp is connect to an Apple Airport Express so that I can stream music off the iPhone or the macbook. Certainly not an audiophile setup, but I’ve never found it lacking.
The BHL kit ($89 direct) comprises the board that you see above, all the parts to stuff the board, instructions, and a bunch of good quality wire. I supplied the Hammond steel chassis and bottom plate and the vintage-style lamp holder and big power switch, plus a $13 24v switching power supply from eBay, some El Cheapo-brand dual RCA jacks, a binding post, and a goofy old Amphenol connector to mate the power supply.
Note that since this thing is running at 24V, I had to try to find a 24v bayonet bulb for the vintage-type jeweled-lamp. Don’t use a 6.3V bulb from yr parts drawer here! It will not end well. Luckily, MCM electronics had 28v bayonet-base bulbs (the closest value that I could find to 24v) for just a few cents. Anyhow, I went through this trouble since I wanted the BHL preamp to match the appearance of the power amp perfectly, but you could easily build this board into whatever you want. Here’s a dude on Instagram who went for more of an ultra-modern/brutalist look for his build. Point is, you can do whatever you like as far as the visual aesthetic yr after. I probably spent about $50 for the non-included components for my build.
The circuit is super-simple and it’s very very easy to assemble. The BHL site has a transcript of the directions that come with the kit if yr curious. It took me less than an hour to solder all the parts together. As Jsn explains on his site, “This is just about the simplest circuit possible that will accomplish what we need – reverse-RIAA equalization with gain. This is 2 JFET gain stages with a passive (no feedback) RIAA equalization network sandwiched between them.” Simple as it is, the components included are of a very high quality.
Now, I was replacing a very cheap phono preamp with the BHL (I had been using a $50 Rolls VP29), so keep that in mind – but here were my initial impressions, which the past month of 4-hour-per day listening has proven to be (subjectively) correct:
*The sound is very good; the low end is a bit more even and less ‘rolled off’ versus the ROLLS preamp. Vocal-area midrange is a bit more forward. The high end seems to sound about the same, but the cartridge/LP is probably the limiting factor as far as treble.
*The biggest improvement is that the self-noise of the BHL is so much lower. And there is less hum. So overall there is really a huge difference in terms of background noise, which just brings out so much more detail in the music. And honestly, I never even thought that my ROLLS preamp was noisy until I installed the BHL.
*Gain is a little lower than the ROLLS that it replaced (maybe 2 or 3 dbs). Not ideal, but not a huge deal.
Full disclosure, and maybe this is unnecessary: Jsn provided the kit to me at-cost. That being said, at the street price of $89 I do still think it is a very good value. If yr thinking of testing the waters of Audio DIY (and you like listening to LPs…), I could not think of a better place to start. Jsn is a great guy, and it was his old BHL blog that was one of my greatest inspirations in starting PS dot com; so if you dig this website, support the dude and get yrself some upgraded sound in the process.

Kinda Miss My Camaro
About 10 years ago I had a dark purple 1986 Camaro Berlinetta with a 305 and the digital ‘knight rider’ instrumentation panel. I bought it for $775 (only 83k miles!) from an old lady who grumbled, “don’t kill yourself Don Johnson” as she handed me the keys. Except for one odd incident in which the car would simply not turn off, it was 100% reliable and I loved driving it. I sadly had to sell it because I lost the parking space it slept in. I was poking around the ole MacBook today trying to find some pics of it, and there ain’t even one! I guess that 2005 was maybe riiiiiiiight before the era of ubiquitous photography of every single fkkn facet our goddamn lives, and maybe I’m better off for it. Maybe Camaro is just better off living in my midnight-blue tinted memories.
While I couldn’t find any Camaro car pics on the laptop, I did stumble on the above-depicted germanium Fuzz Face ‘clone’ that I decorated with a mid-seventies Camaro badge. I buy these old chrome auto badges in lots at the flea market; if yr patient, you can get em for a buck or two each. Anyhow, this is one of the only guitar pedals that I ever built and it turned out great, despite the fact that I simply used whatever old NOS RCA germanium PNP transistors I had around, without so much as even looking at the data sheets. I just tried a few different types until the thing sounded like a Fuzz Face, and voila. One cool detail: in the image above, check out the massive mil-type chassis-mount oil cap (far left) that I used as the output coupling cap.
Above is the very simple schematic that I apparently pulled from FuzzCentral. Much like my Camaro (the car), my Camaro (the fuzz) was sold off many years back, and yeah I kinda miss it. Can’t keep em all…
