1927 Raleigh Mullard Tube Amp

I love the wiring and look of this 1927 Mullard amplifier.
Beautiful!!!!
Early radios produced little power, so extra amplifiers were often added. There was no industry producing them on a large scale, but they could always be built at home, like this magnificent creation of the late 1920s made by PFW Bush. Big amplifiers need plenty of raw power to work on, and this one had a hefty power supply. It also used two valves to drive the loudspeaker, one pushing, the other pulling. A similar arrangement is still used in modern amplifiers. - See more at: http://www.sciencemuseum.org.uk/online_science/explore_our_collections/objects/index/smxg-35205#na

A New Era In Push-Pull Amplification - 1927

A very early 171 Push Pull tube amp article from 1927. Funny since Audion's started in the teens.

National Company Ad

I'm not sure what the deal was with vintage audio companies but they had the most boring names. National Company apparently licensed products from other companies like Catenoid and sold them under their boring name.

GE HAM NEWS 1957

Not Hi-Fi exactly but I enjoy the DIY aspect that was such a large part of the HAM community. There is a a little crossover. Many of the techs I know where also HAM guys. I really like the industrial look of the HAM gear. I have a very large very heavy BUD National chassis that I am going to do something with once I am past a few builds.







I will be posting a few more of these in the coming months.

A HIGH-POWER OUTPUT TUBE - THE 250 - 1929

An early article about the 250 from the Westinghouse Lamp Company.  I wonder if Tesla was still working for Westinghouse in 1929?
  
Here are a couple examples of the mighty 50. The first is my fave as the construction is over the top compared to the others which I am sure are great tubes. But you have to admit they look sad by comparison.

Stephie Bench Designs

Stephie Bench is a name I have heard numerous times from Jeffery and Dave. When I saw a link to Stephie's archive I jumped at it.  I've only just started down the DIY road so I'm reading all I can. There are many things on Stephie's site I'm interested in. I'd lie if I said understood it all but I am catching on albeit slowly. Stephie's archive was saved by the good people at JacMusic http://www.jacmusic.com. There is so much cool stuff here to check out.

 http://www.jacmusic.com/techcorner/SBENCH-PAGES/sbench101/index.html.


Right off the bat I'm most interested in the 2 way active crossover. I've been wanting to use something like this with my jubilees. I like the idea of only having what I need in the crossover without all the extra processing in the off the shelf active crossovers.

Another thing that caught my eye was Stephie's 845 No R No C amp. If you dig in there is tons of information and several No R No C designs. I'd like to work my way up to this amp. It may take a while though. Hell it could take me a while to hoard this much iron..... It would be more realistic for me to do one of Stephie's battery powered amps.

I would be curious what Stephie believes is the best amp she has ever designed. 
Check out the site it is very interesting.

Thank you Stephie & Jac Music.

The Sound Of Denmark - Horns Of Unusual Size

Those Danes are at it again with their large horns. These massive horn sculptures would generate sound and energy from wind.
Art, music and energy generation may seem like unrelated entities. After all, no one imagines a power plant to be pretty, but that's exactly what the Land Art Generator Initiative has been spearheading in the past years with its portfolio of public art installations that also produce clean energy.
  I really hope this happens. Wow......
Great article by Kimberly Mok click here.
