6.3V   2.5A
6.3V   .45A
6.3V   .30A
5.0V   2.0A

Western Electric - Quality Counts

It has been a while since I posted a Western Electric ad. Here is one feature a small segment of their products. Good stuff.. The 713 driver was used on early Klipschorns with the K5 horn. That would have been a two way system.

Electro Harmonix 300B Tubes Being Made - Russian Factory

Great video of the Expo-Pul factory producing 300B tubes. Who is Expo-Pul? They make tubes for Sovtek, Electro-Harmonix, Tungsol, Svetlana, Mullard and others.  


They had a bit of trouble a few years ago. Here are a couple interesting stories regarding the factories history. Articles may be a bit older but a good bit of recent history. They picked on the wrong guy.

TALKING HEADS LIVE 1980

Talking Heads was one of those bands that I love from first listen. This concert is superb I recommend chilling out and watching the entire show. At this point they had been together since 1975.

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
