New Mic Preamp “The Sienna”

IMG_3138Shown above is a pair of Preservation Sound “Sienna” model preamps.  These are the first designs to wear the ‘Preservation Sound’ name.  This is an all-tube design based on the circa 1950 RCA BA2C but with all-mod-cons and 20db more available gain.  It has a true class-A output stage like early broadcast gear.  Three-band fixed 100/1k/10k EQ, fully reciprocal, with defeat switch and flat center response.  Build features include mil-spec tubes, Jensen and Lundahl audio transformers, Solen caps, completely point-to-point wired on linen turret boards with silver wire in the audio path.  Completely enclosed design with internal subchassis for shortest possible wiring paths.  This is a completely unique design that offers a huge range of sonic possibilities.  Defeatable output pad allows user to achieve the ‘overdriven console’ sound of early rock and RnB recordings.  Basic specs below:

Argentine Hi-Fi DIY Circa 1958

Argentine_Williamnson_1958Many years ago I published this article abt digging for ancient audio ephemera in Buenos Aires.   Reader N. Dinapoli Farina uncovered some related materials and has shared them with us here. I believe that the magazine may have been called “Radio Chassis Television” and the scans below are all from the late 1950s.  Click on the images for hi-res.   Enjoy!

Home with Recording Studio For Sale (1964)

LP_sale_1“Only 25 minutes from New York City!”  Download a HQ scan of the original 2-page real-estate flier (‘JD Levin & Associates’) advertising the ~1964 sale of the home of Les Paul and Mary Ford:

DOWNLOAD: LP sale

LesPaulStudio_2I pick up so many lots of ephemera from ancient studios and old-time producers and engineers that I have no idea where this came from, but it somehow ended up in the pile.  My assumption is that someone picked it up at an AES show back in the mid sixties.  It’s professionally printed on cardstock and AFAIK this item has never been interneted?  Is that even a word?  Anyhow, check it out, it’s pretty awesome.  I am guessing 1964 as the sale date because the flier mentions 1962 as a renovation date and LP+MF were kaput by the end of ’64.  HOME STUDIO.  PROFESSIONAL EQUIPMENT.  Wow.

Early Electronic Music

“Think of a sound. Now make it. Any sound is now possible.”

FirefoxScreenSnapz001Contributor T. Fine recommends these excellent pieces on early electronic music.  First, a really fun circa 2006 Australian documentary film:

…And a reminder that the MOMA is still running its “Making Music Modern: Design for Ear and Eye” series:

Moma_Aria_radioIn describing some of the musical objects in their collection, the curators write, “…MoMA was the first museum in the world to collect such objects, beginning in 1932, (and) also pioneered the live presentation of some new music technologies. For instance, Russian émigré Vladimir Ussachevsky performed the first tape-music concert in the United States at MoMA in October 1952. And though the Museum’s collection does not include a synthesizer, it presented the famed Moog synthesizer as a live performance instrument for the very first time on August 28, 1969, changing the course of music history and influencing decades of future instrument design.

The circa 1983 Yamaha MT44 4-track and CS01 synth: examining advertising claims

MT_and_csYamaha used to run these great ads in the 80s featuring their MT44 4-track and cheap lil CS01 synthesizer.

Yama_prod_seriesThey called it the “Producer Series.”  Since I had a CS01 and an MT44, I decided to see what was possible to do with just these two machines.  The MT44 is a regular-speed-deck, so fidelity is not great, but here’s what I whipped up in an hour.   I did not use the dolby cos,,,, i hate dolby!   There are 6 tracks (snare, bass, and bell line were bounced) and the only other piece of kit is a $25 behringer “Analog delay” pedal that’s fkkn awful.  Enjoy!

The Fairchild Model 540 Mic Preamp/ variable EQ/ Cutterhead amp c. 1945

Fairchild_540UPDATE: THIS HAS BEEN SOLD.  IT IS GONE.  I HAVE NO FURTHER INFORMATION ABOUT IT.

Extraordinarily rare, way ahead-of-its-time Fairchild mic preamp/ continuously-variable 2-band boost-eq/cutter-head amp from 1945.  Built as a limited-edition model, very few were made and this could be the only example remaining.  This one was (professionally, it appears) modified very long ago for use with a Magnecord (likely PT6) tape machine, unit is otherwise complete with tubes and a working, good-sounding Jensen Alnico PM8ct speaker.  Mic and line transformers appear to be Kenyons.  Unit removes from its road-case for standard rack-mounting.  Condition poor to fair; needs complete restoration.  With some work this could be the ultimate marquee-rack unit for your world-class studio.   Came to me on a trade and I have no other information on it; AFAIK, schematics are not available online but being as it is circa 1945 technology, it should be repairable by any experienced tech.  Fairchild_540_advert_1945Fairchild_539_540(above: catalog image with companion Fairchild #539 portable lathe)Fairchild_540_nameplate

Magnecord History: The Book: circa 1950

MagnecordIncCoverMagnecord, along with Ampex, was one of the first manufacturers of professional 15ips hi-fidelity tape machines in the world.  While not remembered as clearly as their rival, Magnecord built a tremendous number of machines, and many of them have survived to this day.  We have two at Gold Coast Recorders and after minimal repairs they still work just fine, nearly seventy years after their Chicago manufacture.

Magnecord_Advert_1950I picked up our two Magnecord PT6s at the Elephants Trunk flea market a few years ago for $25 each, and shortly after posting some new recordings made that I with the PT6s I was contacted by D. Boyers, son of Magnecord co-founder John Boyers.  D provided us with an incredible amount of impossible-to-find archival material from Magnecord; you can start to dig through it at this link.

Magncord_foundersFast forward to 2015: D. recently located a long-lost 45pp book that Magnecord created in 1950, presumably for the purpose of pitching new business to the US Government.  In his words:

“I have uncovered what appears to be a very complete book detailing several aspects of the very early years. This 45-page document provides an inside look at the roles of key personnel within the organization, including several photos of workers and assembly facilities in the early factory.

The book appears to have been put together in about 1950, four years after Magnecord was first organized, and it lists several of the early accomplishments of the fledgling company, including their first year of a million dollars in gross sales. (Back when that was serious money)”

You can download the entire 45pp volume (posted as five PDFs due to file size) at the links immediately below:  DOWNLOAD:
