New Linear Audio publication!

[Bksabath]

Code = DIYA

Tanks Dennis

I did not use any code...........
Did I just pay a bit more - or will I not get a LSJ74

you get 2

 

[Tazzz]

Mine arrived yesterday. Here are some measurements I took on the LSJ74-BL with a DCA Pro.

Test Result:
P-Ch JFET
Blue-G, Symmetrical Src/Drn
Vgs(off)=-0,63V at Id=1,0µA
Vgs(on)=-0,12V at Id=5,03mA
gfs=22,8mA/V at Id=3,0mA to 5,0mA
Id=8,38mA at Vgs=0,00V and Vds=6,50V

Usually, the IV curves of Pchannel FETs are plotted in the 3rd quadrant rather than the 1st. Maybe your software automatically plots the absolute value of VDS and IDS? Also the sign of VGS is backwards; a Pchannel FET cuts off when VGS is a large positive number.

Got my copy today

Hilarious!
How do you find these things ??

Its DIYA, but don't tell anybody

First day of AES in NY today. If you are attending, stop by at booth # 2560 (combined audioXpress / Linear Audio) for a chat!
I also have a limited number of issues available.

AudioXpress are making an effort, contents has increased from 48 to 68 pages. Cover story is an amplifier review by none other than our own SY! Get a free copy at the booth!

Jan,
Is there a parts list for the Putzey preaamp?

 

[Mark Johnson]

Is there a parts list for the Putzey preaamp?

"Table 1: full parts list" appears on p.123 of Bruno Putzeys' article in Linear Audio Volume 5. To cite one example, the 26th row of this table says that R24 & R54 are 2k2 resistors in the 0805 package.

I have the publication, but sizing is not included on many of the components. Some are smaller than I have used and I am just trying to make sure I purchase the correct ones.

Hmm, gotta find my AES card...maybe I will take the train into the City and stop over.

Bear Meets Jan

Guess this might be the place to post the historic moment, at AES.

 

[jan.didden]

Yeah.... coming out, sort off, isn't it Randy
Nice of you to stop by for a chat!

Jan

 

[jan.didden]

This was anyway a good trip for me! Met people like Bob Cordell, Ed Simon, Stuart and Cynthia Yaniger, Scott Wurcer, John Curl, Gary Galo, Kendall Castor-Perry, David Moran and a few others I probably forget to mention (apologies), I enjoyed the talks, whisky/wine/beer and dinners!

Jan

 

[bear]

Oh drat!

Ah well, would have loved to have met everyone on that list that I had not before.
And even Curl who I have met. I did run into Ed Simon and had an interesting chat.

Must have been there on the wrong day.

I did take my bear suit off for the show.
And since one of my main aims for the show was to meet Jan, mission accomplished!

_-_-

 

[jan.didden]

Forgot to mention (of course) Mark (Variac) and his wife Maria-Elena who hosted me in SF and even took Scott and me and a few others out sailing, and meeting Jason, diyaudio's owner. Met wavebourn/Anatoliy and his better half at BAF too.
Enjoyed lunch with Vladimir/AR2, one of the original BAF founding fathers.
OK, that's enough name dropping for this year...

Jan

 

[bear]

Do you have photographic evidence to prove these allegations?

 

[jan.didden]

See if you can identify Scott, Mark/Variac, Jason and moi.
The Alcatraz backdrop is just coincidental.

Jan

 

[bear]

Pirates on SF bay, is it then?

Can't say I can identify any of that crew of scoundrels, but they look mighty suspicious to me!

 

[jan.didden]

Free Linear Audio anyone?

I have an excess Linear Audio Vol 6 and a Baxandall & Self on Audio, in Minnesota.
For free if you want to pay the shipping, as a pair not separate.
First come....

Jan
