Gates M6244 and M6244B broadcast phono preamps c.1960s

above: a pair of GATES M6244 phono pres; these are the early version designed for use only with the 6200 ohm GE “Variable Reluctance” -type cartridge.

Happy new year y’all. Been a good long while since i’ve posted anything besides my radio playlists. One reason for this is that I’m so much busier than I was 12 years ago when I started this blog; between my regular job and my new brewery operation I don’t have two spare minutes to rub together.

The other reason, though, and this is a major factor, is that there is now so much less of a need for what this blog did: displaying technical ephemera related to audio gear and audio production. When I created this blog, almost of all this sort of discussion happened on internet ‘news groups’ and ‘forums’; there were few blogs, or websites, devoted to making this kind of material available on a semi-permanent basis. Now there are 100s, probably 1000s. It was the case 12 years ago that I would, everyday, pull some piece of old paper out of the shop and sure enough: no one had yet made it available free online. That’s just not the case anymore. In the past decade, many many many folks have created resources like Preservation Sound, and nowadays almost every piece of ancient tech lit I find *already* has a home on the web.

Well, that wasn’t the case with these two things. Above is a pair of GATES M6244 broadcast phono preamps. Tried as I might, I could not find schematics for these things; nor could I find an answer to the mystery of why there are two *different* circuits with the same apparent model number.

The two identical units here that I found and partially recapped are, unfortunately for me, the early M6244 which are designed to work the GE “VRII” variable-reluctance cartridge. Now, this cartridge *is* fairly common, but only as a mono cartridge (there is apparently a Stereo version of the cart, but its very rare, i’ve never found one, and its pricey online). Almost every good-quality phono cartridge sold since the 1960s has a 47,000 ohm impedance – a significant difference.

above: the schematic for the original version of the M6244, designed for use with a 6200-ohm cartridge.

According the manual, in fact, this preamp derives its RIAA high-frequency roll-off spec from the relationship b/w the 6200 ohm cartridge impedance and R3, the load resistor. The low-frequency characteristic is derived from a feedback network between the two transistors.

above: the manual for the original version of the M6244. Check out the ‘circuit description’

The M6244B, which I was not fortunate enough to find, is designed to work with a now-standard 47K ohm cartridge. If you look at the schematic, you will see that the feedback network between the two transistors is a bit more complex; this is because in THIS design, both the low-frequency AND the high-frequency compensation occur via this network:

Alright. So here’s a question for all you more-knowledgeable types out there. I’m no engineer. Is there a relatively EZ way that I can modify this pair of m6244 to behave properly with a 47K ohm cart? If these things were point-to-point wired (IE., not a pcb), I would simple re-build them following the m6244B schematic. But that would be too much work with the PCB -style construction -they are too different in design. Any other ideas? For what its worth, before I was aware of this impedance ‘issue,’ I tested the two units with a deck loaded with a garden-variety vintage SHURE cart (spec’d at 47K ohms), and it sounded absolutely fine to me. Any thoughts?

Bell Labs’ Electro-Mechanical ‘Speech Synthesizer’ circa 1951

**update 07.09.21 – audio clip added! see below! you can now HEAR this monstrosity!**

Download a 4PP article (+advert) from the June 1951 RADIO ELECTRONICS on the subject of a novel (+fairly creepy) electro-mechanical speech-synthesizer designed by Bell Labs.

This has got to be one of the wildest electro-mechanical synths every created. I wonder what New Jersey basement it ended up in. I’m preeeeetty sure that this abomination provided the historical-basis for the device that Tony Shaloub’s character was developing in the first season of The Marvelous Mrs. Maisel. Anyhow. It’s weird and far-out and I think you will enjoy reading about it.

T.F. provided us with this audio clip so that you can hear this device in action. it’s pretty remarkable TBH…

Bogen DB20 Equalizer Circuit circa 1953

From the October 1953 edition of RADIO ELECTRONICS comes this report on an exceptionally powerful EQ circuit as-found in the then-new Bogen DB20 amplifier. The circuit uses no special parts and promises extremely wide-range control. R11 is odd, i’m not sure why that is present. I’m thinking that this might make a good EQ circuit for the Berlinetta DJ console…

“Better Is Gold”: Debut EP from Enid Ze: Available now

Now available: the EP ‘BETTER IS GOLD’ from Enid Ze. 

You can hear it via the platform of your choice at this link.

Enid Ze is a musical vision conceived and directed by Zimbabwean-born singer/songwriter Nyasha Chiundiza, produced and mixed by yours truly, with invaluable aid+participation from so many of my most dear musical collaborators.  It is not lightly that I tell you: Nyasha is a visionary and an iconoclast.  Here’s some words about the project from the man himself, but please don’t take his (or my) words for it.  Check out the tracks.  This is something else, and something wonderful. From NC:

enid ze is a continuation  and reimagining of the Southern African tradition of Zamrock—W.I.T.C.H. Keith Mlevhu, Wells Fargo—where global pop and rock come to cohere in specific existential experiences of living many worlds at once. Listen to the panting on the title track “Better is Gold” and remember Letta Mbulu. When you hear “Marechera” recall modernist African writer Dambudzo Marechera’s poem, Punkpoem:

In the song

Are waterfruits;

In the plush and flow

Firestars eternally fixed.

Guitar strings lash

My back, draw blood –

The out of control voice

Skids shrieking across

Tarmac audiences.

When you hear “Shuwa” hear the word “sure” but also the  waves on the beaches of Maputo, Mozambique. Or the beer gardens of downtown Harare.  Also listen to how far home and how close it is, how unrest and rest lie together like a lion and lamb.

“Better is Gold” is about the condition of seeking more than you see—not in the future but in the things that you find along the way. “Better” is better than gold.

“Derniers Préparatifs”: new CAMERRO single for download

Download my new track “Derniers Préparatifs” here:

Eight days ago I found an ancient Italian polysynth at a local pawn shop. Called the Crumar Orchestrator, it’s an odd combination of string synth, ‘electronic piano,’ and monosynth all in one rather heavy package. The sound is effortlessly evocative of circa 1980 Euro cinema, and this track came to me instantly. You can see pics of the Crumar, hear my original live performance of the piece, and even see the drumkit mic’ing for this track at my Instagram page.

As with the rest of my Camerro project, this track was recorded entirely on a four-track cassette recorder: in this case, a Tascam 134. Here’s how it went down:

Track 1: Ace Tone ‘Rhythm Ace’ drum machine w/heavy Yamaha E1010 16th note echo; Track 2: Crumar orchestrator (this is the bulk of what you’re hearing). Track 3: Bass guitar. Track 4: add elec guitar while submixing with tracks 1, 2, 3.

After the bounce, I added live drumkit to track one (overwriting drum machine), and add two passes of Roland Alpha Juno synth + Hohner Pianet electric piano to tracks 2+3 (overwriting bass+ Crumar). The kit was recorded with two mics, submixed thru a basic mic preamp and heavily compressed to tape.

“Song To Welcome The Spring”: New CAMERRO single for download


SONG TO WELCOME THE SPRING /// the first track I’m releasing from my solo recording project CAMERRO. 

‘control-click’ on the player below to download the MP3.

This song is inspired by my trip last yr visiting ancient pagan churches in Estonia.  Everything you hear is played live by me and the track was entirely recorded on a cassette 4-track.  For me this music is as raw and personal as it gets.  The 4-track cassette process requires that everything be performed carefully and with great intent as ‘fixes’ are not possible. For yall techy-types here’s how it went down:

Tascam 134 4-track cassette deck with Maxell XLII-S tape. Click to track three, elec gtr (finger picked rh+melody) to track one, drums to track two, bass to track four;

Submix gtr, drums, bass while playing congas all to track two (erasing click);

add electric organ on track two (overwriting drums), add sitar and cello (in sections) to track one (overwriting gtr), add percussion to track to 4 (overwriting bass). Two microphones were used: Bang&Olufsen ribbon for drums and perc, Neumann TLM170 for congas and cello, gtr bass sitar organ were direct. FX are Yamaha PROR3 reverb and Yamaha E1010 delay.

“Bully. Coward. Victim. The Story Of Roy Cohn” w/score by Ruggiero and Halpern: HBO debut

Tonight Thursday June 18 at 9PM: “Bully. Coward.Victim.” will air for the first time on HBO. Nathan Halpern and I scored this outstanding documentary for director Ivy Meeropol, our second collaboration following her award-winning 2015 doc “Indian Point.”

Cohn was an infamous and complicated figure, and Meeropol’s film paints a detailed and nuanced portrait. The incredible, horrible closeness that Meeropol has to Cohn gives her a unique vantage point from which to tell this story.

This was a wonderful project to work on; I got to create music in a variety of styles that I don’t often get a chance to play with in a film context.
