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.

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!

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.

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!

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. :p 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! :D

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...

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....
