Vacuum tube modeling software - beta testers wanted

[andrei]

You mean these?

Hi Andrei,
Yes those are the ones.

I find Curve Captor is an extremely useful tool, and works really well. I'm glad that you put what was obviously a considerable amount of effort into creating it. Thank you!!

Any possibility that you will eventually add support for pentodes and tetrodes?

I am currently using it to create models for less popular triodes like the 5744.

I will share any models I make via this thread.

Just a note for those installing on linux, it will not compile with gcc 4.1. Install gcc 3.3 and edit the makefile to make it use that version of gcc. On ubuntu the generic gcc executable still points to the newest version installed when you do this, but you are able to invoke gcc-3.3 explicitly from the makefile. It will probably be similar for other distributions.

I also needed to change the paths in the makefile.

PM if you would like my makefile.

Now I just have to learn how to use it.

It work fine here on gentoo with gcc-3.4.6.

A question about the compile flags in the makefile. Are you sure about the -O3 flag? I ask this because I get wrong simulation results with the nec2 software (antenna simulation) and -O3. The best solution was to use -O2. I also know that -O3 can break the precision of FFTW.

I also get a warning :`-mcpu= ' is deprecated. Use `-mtune=' or '-march=' instead. I removed -mcpu=ipentium4 and changed march into -march=pentium4 (the same as my processor).

Andrei,
When I click the "build model" button, Windows displays "tubefit.exe has encountered a problem and needs to close". What's wrong with this do you think? I run it on WinXP SP2 platform.

Sounds like a core dump, but hard to tell what caused it. Try 'tubefit -h' from command prompt - this should just print the usage message. If it dumps core again, it is probably the runtime libraries problem...

Thanks, Andrei,
It's OK now, I suggest you make some more buttons like : File|Open, Close; Delet Marker or Move Marker ..

Hello Andrei,
impressing work - especially when ome has tried older curve fitting programs !
For me the program seems to work OK - winXP - but I have a problem :
When drawing curves the pro Voltgram insists on making curves for each 1Volt grid voltage, which is somewhat overwhelming when the range is from o to -200V ! - does a control exist somewhere under
the surface ?

Thanks in advance

I have been following this thread and I just want to say that you are all amazing individuals. I have headache just from reading the thread.

 

[andrei]

Who is this pro Voltgram and why is he insisting on things?

Seriously though, the curves are drawn based on Vg values for points you give it. It's a simple algorithm, and it could make a stupid choice. If you send me device data you are tracing, I can take a look...

Hello Andrei,
seems like a hardware quirk - I installed the program on my stationary PC instead and all problems disappeared without any explanation !
Super working - but I concur in that an easy way of removing/moving faulty points instead of editing a list of hundred points would be nice.

Kind regards
Jan

Hi Andrei,
You helped me a couple of times in the past with getting your great program to run on my machine which it does to this day. The above suggestions would be great if implemented should you ever have the time. (Thanks for taking the time to create this in the first place.)

SV572 Model

I've just created the new model for Svetlana SV572-3.
U can downoad it at my personal page

Hi Andrei,
Very nice tool you created.
My friends and I like it so much.
We are discussing and exchanging many experiences about it at http://vnav.vn/forum/viewtopic.php?f=9&t=8845&st=0&sk=t&sd=a (Sorry, Vietnamese only)
Hope new version release soon.
Regard

First off I'd like to give andrei kudos for Curve Captor!
I had a lot of free time on my hands last summer and made a butt-load of triode models using Curve Captor, soo I thought I would share them with you all. I bear no responsibility for any damage that you do to yourselves, your pets or your property by using these models: use them at your own risk...

Includes PSpice, LTspice, 3f4, CircuitMaker models and PSpice models for MicroCap6.
tube4.lib is a library I used in MicroCap6 for testing. I hope you can use them and enjoy!

Cheers,
Wayne

Hi Wayne,
Finally I got the EC86 that I did not have earlier. Seems to work perfectly in LTSpice
Thanks

patch for gcc4

In case anyone else has trouble building on gcc4, here's the patch from Andrei that builds (except I added .txt extension to conform to upload file types)

Yea!!!!!!!!

Thank you.

Digging up an old thread here as I have downloaded the mac version and it looks useful (at least for triodes) but is confusing as h**l to operate with no instructions. Is there a tutorial page? I was able to load a gif but the picture is too large and I can't figure out how to resize. Also it appears that I have to mark the axes and curves but not sure how to do it.

 

[platplaas]

I am trying to figure out the mac version as well. The one I downloaded here doesn't seem to do anything? Do I have an old version? Thanks.
