Incredible collection of early radio and audio on auction now

I was recently hired by The Westport Auction Company to catalog and research an incredible collection of early radio and audio. Charles O’Neil operated Bridgeport’s radio repair shop from 1935 until 1970. He amassed an enormous collection of artifacts that are being offered for the first time. Visit Westport Auction dot com and follow the link there to register to bid. 
This is a one-of-a-kind, complete, unpicked collection of 1870s to 1970s radio, audio, early mechanical instruments, and more. Highlights include a circa 1931 Emicon, possibly the first commercially-produced synthesizer, and possibly one of only two surviving examples in the world.  There’s a great amount of early Western Electric items, and some fascinating ephemera lots as well.
Check out the catalog at @westportauction, read the terms there, and register to bid. Full disclosure: I am employed by Westport Auction for the auction.

How to add Silicon Fuzz to any tube amp (!) (1969)

Got a good one for you today. Below is a 1969 article from “Science and Electronics” magazine (auth. Herb Friedman) that describes an incredibly simple way to add an adjustable, defeat-able silicon-fuzz circuit to any tube guitar amp. I haven’t tried this yet but i am def excited to. If anyone builds this out, please comment and let us know the results.

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.
