I recently needed a pair of working Weston 862s. I only had one busted one, and a pair of 861s with different gfx that Weston OEM’d for some other firms. So i’ve scanned the 862 panel at 600DPI and I am going to attempt to print and re-cover the panels in the 861s. Wish me luck! Here’s the art at 600DPI if anyone else needs it:

G. Frudd worked at ADM technology from 1976 – 1989. He sent us the photos above and below. These document some of his work at ADM during that period. Frudd started at ADM as the “console fitter,” previously having worked as a tool & die maker.

Frudd went on to run all of the mechanical shops- machine, cabinet, engraving, and fitting, eventually becoming the Mechanical Engineering Manager. Frudd was directly involved in the design of all consoles and rack products during that period.

G. Frudd: “In my time at ADM we transitioned the product from wood cabinet based to metal and extrusion based structures. It was a great and exciting place to work. After ADM’s demise I went on to be a mechanical designer and product line manager at several companies in the lighting and automation industries.”

The two images above are burn-in racks for console modules.

Thanks for sending in these great images GF!

When State House New Haven asked me last month if i’d be interested in opening the first-ever New Haven appearance of Anika, i think I said YES halfway thru the “…ka.” Her 2010 Stones Throw LP, produced by the legendary Geoff Barrow, he one of my all-time greatest musical influences, is one of my 5 or 10 favorite albums of the past decade.

Nyasha Chiundiza is a tremendous singer+songwriter whom I have been working with the past coupla years and we’ve put together a set of all-new material especially for this show: a six-song suite based on ancient Russian folktales titled ‘Russian Folklore Variation #127.’ It is something else. We are super-excited to premiere it for you. Get tix here.

Several years ago I received a telephone call from a man named Johan VanLeer. VanLeer designed reverb systems for Hammond many many decades ago, and later developed a very rare spring system for Quad Eight. He sent me some interesting information regard the Quad Eight system; click here to read that earlier post. VanLeer is still developing new spring reverb approaches to-this-day. Here is a bit of of info on his latest project.

“Still tinkering with spring (4) reverberation systems, I thought updating you. Due to the 17″ rack width dimensions, the DELAY TIME is limited to the spring length, which has to be less than about 13”.

To double the DELAY TIME I constructed a few systems by using and updating the 1964 US Patent No: 3,159,713 by W.C. (Bill) Laube, Jr., like me, a Hammond Organ Co. Engineer.
In the so called “single ended system” both the receive- and send transducer are on the same side and the other side has the spring-ends firmly anchored.
So, the send-signal bounces back  doubling the delay time before it reaches the  receiving transducer.
To avoid cross-talk from the sender (1 coil),  the 2 coils of the receiving transducer are connected out-off-phase.
