June 1961 Installation Of The Month

I really dig the retro built in stereo systems. You don't see much of that in this day and age. Check out the system components. Very nice.

Dengue Fever - Cambodian Inspired Rock

This band is inspired by the Combodian rock before the Khmer Rouge. I think two of the band members are Cambodian. I get tired of the same old music and while surfing for new music my friend Byron said hey search Dengue Fever. They are pretty good for being half Cambodian and half California hipster. The sound is good and videos fun. The lead singer is my favorite part of the band.

Calix Horn Speakers

The Calix speakers are hand made in Taiwan. I picked a couple examples I thought were interesting but they actually have a broad product line. 
The Neoclassic is a nice design but it would have been nice to integrate the tweeter into the cabinet. 

The Phoenix family of speakers are really interesting looking with some nice features. The product line has five different models.
I like the height adjustment on the mid horn. 
 External crossover.
 Just in case you needed some bling here is the diamond version.
 300lbs each.........

Horn Of Unusual Size

This is one long bass horn. The construction is nice as it seems to break down into at least 4sections for transporting. 

If anyone has additional info on this horn I'd love to see it.

1960 Stereo Cartridges Have Personalities

This is something I try to ignore. The road to cartridge rolling can be expensive and as addictive as heroin. I use bang for the buck cartridges like the Denon DL110 and Ortofon 2M Blue or whatever I happen to score on vintage gear. Recently I went back to the 2M Blue and I was surprised by the difference. The 2M will be staying on for a while. When I was at LSAF a few years ago Dave Slagle has a turntable fitted with 3 carts. I tried to ignore the effects of changing carts but it was impossible. It is a road I'll have to go down eventually

1963 US Army Training Film Amplifier Theory

These videos were posted over at the asylum by Samra. The animations are great.

If you search youtube for Navy or military electronics training videos the selection is pretty good. The basic info is still the same.

Klipsch Historical Archives Online

 I don't go to the Klipsch front web site very often so it seems I missed a major site update. Klipsch engineer Jim Hunter has spent years going through PWK's documents and preserving these historical documents in digital form. Fortunately Klipsch is dedicating a portion of the site to host these documents. 
 You can access the some of the new sections of the site here.

Here are a few examples of the rarities posted. 

Metal printing plates.
Early picture of Klipschorn construction.

It is very interesting that PWK was also interested in phonograph pickup design for many years from 1940 to late 40's.

This is my favorite section  a collection of PDF documents with Klipschisms, quotes, and anecdotes.

Paul's original oscilloscope was a 1930s DuMont model, with similar amplifier for horizontal and vertical. His typical way of using it was to put the output of the audio oscillator into the horizontal input and the output of the item under test, through an attenuator, to the vertical input. Thus the relation of the two was the inclination of the line or ellipse and didn't require keeping the oscillator output constant as its frequency varied. He later (1950s) bought a Precision scope, allowing the DuMont to be used for production testing. -- Jim Haynes

 In the mid-1950's, when Paul came to Boston for the HiFi shows, we would have our Klipschorns along with Marantz amplifiers and Grado cartridges in our demo room. With the usual Harvard and MIT fans around him, he sat down on a Marantz power amplifier. Soon we smelled a peculiar odor, and for a moment thought some competitor had put a stink bomb in the room. Just at that moment Paul gave out a Klipschorn-sized yell!! He turned around showing his bottom to the gathered group of admirers saying, "Look what that "adjective/noun" amplifier did to me." There were two clean burn holes from the output tubes clear through his wool trousers, boxer shorts, and his seared rear end. It wasn't long after that Mrs. Marantz came into the room. Paul went to her, bent over and said, "Look what your amplifier did to me!" He later spent a good deal of the show trying to get Marantz to pay for his trousers" -- Don Davis

Go to the redesigned Klipsch site and check out the new PWK historical information posted. I only posted a few examples. I understand Jim Hunter is going to keep adding information to the site which is great news. I'm still waiting for his book because he is the one to write the book on PWK.

War Of The Worlds Speaker Ident?

I have seen this picture floating around the internet but I have no idea the history behind it. Anyone out there know manufacturer or any other information?
The speaker system does remind me of SciFi movie war of the worlds.

The BTH K10A

Nice spec sheet for the BTH K10A. These are very rare. If you want to find these you need to be in the UK or Canada and even then they are very rare..

The Silent Partners Part 2 - August 1958

Here is the second part of this great article The Silent Partners. They should have done part three for the cartridges to round it off.

The Silent Partners Part 1 - July 1958

I love these old turntables and tone arm articles. This one is from 1958. The first part is turntables and the second part is tonearms.
