Try to find a Low Cost Fairchild 255 in this day and age. Don't think it will happen.

Jensen High Fidelity Loudspeaker Line

From the Unax to the Triax Jensen ad. The Jensen marketing machine sure had fun with names like Unax, Duax, Coaxial and Triaxial speaker offerings. Of course vintage Jensen ends at the G610.
I wish I could still get the free data sheet.

Technics SL-P1200

After 1400 posts I'm posting a CD player. Never thought it would come to this but I've always wanted one of these top loading broadcast cd players from the 1980's. It has nothing to do with sound quality. I just like the way it looks. I might be sick.... It could be something serious. Next week I promise to make up for it with plenty of broadcast turntables.

I should have posted this on April 1st.
Feeling digital dirty.

The Anarchestra

This guy Alex Ferris is brilliant. I tried to classify his sound but just stopped to enjoy it for what it is which is amazing.

I'm going to sample the many albums on his site and then buy a few.

 The influence of Harry Partch lives.

OHMITE Resistance "Know-How"

This vintage Ohmite reisistor ad reMINDS me of the Twilight Zone. This ad is a little creepy to me but I dig the brains.

Ton And A AQuarter Of Sound - Audio 1964

This system looks like many modern DIY efforts but this one is made of concrete. How the hell do you move this? Position for sweet spot? Woah... Still really nice article from Audio one of my favorites.

Brook Electronics Let Your Ears Pass Judgement

Another early Brook Electronics ad. I've found a few more of these while researching the 12A. I hope to do a 12A clone this year.

NEC 50CA10 Triode

The 50CA10 is a triode tube built for Luxman by NEC. It doesn't get much mention because originals are very rare. Fortunately Shuguang has started producing them again so I don't have to panic. I've been waiting for Thomas Mayer over at Vinyl Savor to write about them because I do not have very much information on them and his write ups are great. Don't expect any tube dissections here.
 There are only  two amplifiers that I have found that actually used this tube. One of them is the Luxman MQ60 which is a 30WPC Push Pull amp . Now that the Shuguang is manufacturing these tubes again I've seen several DIY amplifiers use them in SET and Push Pull amplifiers.
 Here are the well used and loved 50CA10s my Lux MQ60 uses. They will need to be replaced soon I'm sure.
Here is a pic of the replacement option from Shuguang via Leisure Audio.
 And the not in English Datasheets. 
Yes that is 50v .175a heaters.

1930's Knight Tube PA Amplifiers Ad

I didn't realize Knight was operating in the 30's. These are for PA systems of the day and were operating at higher wattage into Class B.

Brook Electronics - All Triodes

Yet another Brook Electronics ad. Good marketing towards the triode crowd. I would love to get my hands on the Brook booklet "Better Listening".
