For those who might be interested there is a black version of the 909X on eBay with an auction end day of Monday early afternoon. The condition looks good from the pics (of course buyer beware!) and current bid is $127.50 with two bidders. I have one of the white series which bought several years ago from another ham right at this price, so needless to say I was happy (and lucky!)

Tubes and Valves: Dan’s research uncovers three vintage films

Hammarlund-SP-600

Many thanks to SWLing Post contributor, DanH, who writes:

I have been working on my Hammarlund SP600-JX-21 for the last two weeks. Results of the filter cap replacement were encouraging. I’m going after an AVC issue that is probably capacitor-related as well before doing a re-alignment with the signal generator.

All of this activity has turned my attention toward vacuum tubes. I found three vintage industrial films online that caught my interest…

The Mullard Radio Valve Company produced The Blackburn Story in 1962. The film was shot at what must have been close the peak of vacuum tube mass production. This presentation is unique in its finely detailed documentation of miniature tube construction. The hand labor required to build some of these tubes is incredible, considering it is a mass production operation. A surprising degree of automation is present for manufacture of some of the more popular tube types. The video resolution is not the best but I found myself ignoring this limitation after the film got underway. I have a few Mullard tubes in my tube boxes.

Western Electric presents A Modern Aladdin’s Lamp (1940). This look at the electron tube is hosted by none other than Lowell Thomas. From the age of four pin and octal base tubes animation shows how tubes work.

Electronics at Work (1943) is a WWII offering by Westinghouse. The description of vacuum tube technology is a little more detailed and again animation is employed for visual impact. A variety of vacuum tube applications in industry and the military are shown from curing plywood to producing X-rays. The excellent animation was contributed by Famous Studios (when they weren’t doing the wartime Popeye cartoons).

Wow–thanks for sharing these excellent videos, Dan!

BBG Watch has learned that a proposed privatization of the U.S. taxpayer-funded Voice of America (VOA) is widely opposed by Broadcasting Board of Governors (BBG) federal employees, their union, the independent Committee for U.S. International Broadcasting (CUSIB – cusib.org), and numerous foreign policy and public diplomacy professionals, as well as some former VOA journalists. At the same time, critics of privatization of America’s “Voice” strongly support structural reforms of its ailing federal agency, the Broadcasting Board of Governors, which they blame for VOA’s troubles.

“A decision to reform the Broadcasting Board of Governors merits its own separate bill where both houses of Congress can debate and carefully consider the best course of action,” AFGE Local 1812 union told its Broadcasting Board of Governors members. “It should not be addressed in a stealth last minute amendment to the National Defense Authorization Act,” the union said. The union urged BBG employees to contact their senators and express their opposition to the amendment submitted by Congressman Mac Thornberry and “the offensive language is contained in section 310 (b) of the amendment.” The Senate version of the bill does not have this language, the union reported.
