See curve captor free download - SourceForge

Hi, this software is very good. Can you share this software?,

Here you can find the Windows compilation, upon unzip run "curvecaptor.tcl" from CMD or file manager, it runs but the image file open only partially not full image, any idea what's up?

Edit: I resize the curve screen shoot image to 800x600, it's fully display.

More info found here.

Here you can find a triode connected curve for VF14, (similar to EF14). I just trace it with CurveCaptor and model generated and work in LTSpice.

* ef14-3 PSpice model
.subckt ef14-3 P G K
Gp P K VALUE={(0.07667528023m)*limit(V(P,K)*log(1.0+(0.01432477678)+exp((2.400438702)+(2.400438702)*((27.36298562)+(-3289.702555m)*V(G,K))*V(G,K)/V(P,K)))/(2.400438702),0.0,1.0e16)**(1.33452029)}
.ends ef14-3

Here the tutorial in social media.

Does any one have triode model for 3V4/3A4? I searched the thread but couldn't find it. Thanks.

I painted this 3V4 Tung Sol, included screen current and triode Mu est 9. Attached is the pentode and triode connected plot. The inter electrode capacitance can be changed if necessary.

Oops, this is the correct triode plot (model has not changed).

pli · 2017-07-20 3:11 pm

That is great. Thanks. I did a line stage with 3V4 in triode mode and it sounds pretty good. I am on travel so I don't have the exact numbers. If the memory served me correctly, I biased at Vp=80V, Vk=4.7V, plate current is around 9mA, which is very close to your plate curve showed. Excellent work!

Doese any one have 6463 SPICE model and EF804S both triode and pentode SPICE model.I have tried to find them in thread,but could not find it. Any input will be great appreciate.

Have tried 6463 ,EF804S Triode-Connected SPICE Model,it worked well,but for the WE437,it seems like incorrect,the current of R66 shows -0.0116409.attached the screen short and the LTSPICE files.

Best Regards
Leo

jazbo8 · 2017-08-07 4:43 pm

You may want to check the LTSpice manual wrt the current flow convention.

Try reverse the direction of R66. I found that long ago, not sure why the current phase is reversed.

Edit: in other sim, it shows the direction when you bring the cursor over the components, so please note.
