I had to go solo this year, while Tam stayed home to meet the AT&T tech. This meant, of course, that I lacked even the modicum of restraint she sometimes adds--
The two large devices are a 1940s Meissner Analyst, which is a kind of "test bench in a box" for receiver servicing, and a 1950s Harvey-Wells Bandmaster, a 25 to 30 Watt AM/CW amateur radio transmitter. Both appear to be pretty clean; the transmitter needs an external power supply, 400 V at 200 mA.
Other neat stuff: a pair of vintage binoculars in good shape -- didn't have anything but toy versions, so for $35, why not? -- a very good push drill with straight bits and a "Handyman" Yankee screwdriver, a full set of Birnbach ceramic antenna insulators, chassis-mount octal plugs (good for power supply connections), three General Radio mixer knobs, a couple of Dakaware knobs, a National tube socket and 100 pF variable cap, another 100 pF dual variable capacitor, an SW-3 coil form, a 6F7 tube (possibly for a project) and a pair of 6L7s (used in my microphone mixer). Plus four 1940s/50s QST magazines, three quartz crystals and and assortment of other nice small parts. Not shown, a short (10'?) desktop rack and a large toroid core to wind a balun on (you want 'em big -- magnetic saturation is lossy and can produce a lot of heat!).
I met my dear old friend Don H., and several other people I know slightly, including the talented Jim Borgioli,whose ham work includes building very nice AM transmitters that run at or near the legal power limit. And one ham who knew me! A young man who'd gone looking for info on the Stancor 10-P transmitter and found my postings about it on Retrotchnologist walked up to me in the flea market area, asked, "Are you Roberta?" and introduced himself.
Found but missed a nice balanced antenna tuner. I should have purchased it at first sight! But it's a cloneable design and I think I have the parts.
A fun time! When I returned home, the phone tech was there -- and pointed out a very large broken limb on the roof and my ham antenna and still loosely attached to the tree. I climbed up and had a look, but it's too big and too precarious for me. We've called the singing tree hippie, who does great work at a fair price.

Nice haul!
ReplyDeleteThat much stuff, in that nice of condition, would cost you a small fortune out here.
And that reminds me....I have to go to the TRW swapmeet this month. Next month is the last one ever unless they can find a new place to hold it.
I thought you should see this http://www.popularmechanics.com/military/research/a16853/darpa-vacuum-tube/
ReplyDeleteI found a time sink you might be interested in, it is most all of the Popular Mechanics magazines from 1900 forward. It has a lot of stuff from the dawn of,"wireless telegraphy" and early radio, including how to build your own equipment.

It is totally free, has some of the early racial stereotypes unfortunatley,but all in all is a very interesting site. I think you might enjoy it.
