I've added a new addition to my Clough-Brengle collection.
After the Swap Meet Saturday morning Robert Lozier and I took
a little road trip. First we stopped in downtown Greensboro
so I could take some photos of the building where Johansens
Electric was located in the late 1940s. This is for a future
article I'm working on about my Clough-Brengle transmitters
for QST. Johansens is the store where they were sold a
war surplus in 1948.
After this we drove about 75 miles to Hurdle Mills, NC to
visit Larry Dowell and see his radio collection.
Larry has a really big work shop where there are literally
hundreds of radio cabinets and chassis stored waiting for
future repair or parts removal. One thing he has that I really lusted over is a large commercial
grade glass beading cabinet, it is really nice.
We also got to see Larry's car collection.
Just before we left Larry took me back into the shop
and pointed to a high shelf where a dusty Clough-Brengle model
79D was sitting. He asked me if I wanted it...
Well yeah, I don't think I've ever turned down a
piece of Clough-Brengle gear, even though I wasn't
totally sure I didn't already have one like it.
With about 40 pieces of C-B test equipment in the
collection it's hard to keep up with what I have
already. Well s it turns out I didn't have a 79D,
I do have 2 different model 79Cs, so the 79D fit nicely
after some shifting around. It's missing the eye tube,
Larry said he swiped it to use in a radio.
No problem, I'm sure I have a replacement.
If you're interested you can see the new model 79D
and the other pieces in the collection by going here;
just scroll down toward to bottom and you'll see a
photo framed in RED with a RED "NEW" above it,
this indicates what is the newest addition or
recently updated pages.

The photo below shows the 2 model 79Cs on the
left and the 79D on the right.

Take care and thanks for visiting.

Congratulations Ron!.

For those not familiar with the (miniscule) world of Clough-Brengle collecting, there are several models of test gear that were produced by C-B that are literally "scarce as hen's teeth". The 79 D would fall into this category. Along with the OB audio oscillator, UC voltmeter, and all C-B communications gear.

As probably the second largest collector of C-B equipment (I have around 30 pieces), I can attest to the rarity of this generator.

Just this past week, I finally scored a big one with the acquisition of a Model 88 VTVM. This meter, produced somewhere between 1935 to 1937, never crops up. I certainly have never seen one in the flesh, and know of only one other, and that one belongs to Ron Lawrence. Using the fan style meter, these VTVMs only measured peak-to-peak and RMS AC currents, with a range of 0 to 100 volts p-p, and only 0 to 1.2 volts RMS.

And Ron-I have gotten the meter in safely from shipment. The seller is a long time ham, and had the meter sitting in his shack for years, and just decided to to downsize his collection. His packaging was superb, with heavy double boxing, and solid foam to act as cushion and barrier. The meter itself was literally cocooned in bubble wrap. The unit is in beautiful condition, unrestored, and apparently has never been tampered with. All knobs, the switch, and button, are there and in good shape. Still has the 6J5 tube (probe) in it's housing with original lead.

The only thing missing is the power cord. That, of course, can be easily fabricated.
