However, how can I change the Y-axis? I wish to create a much lower load resistance slope than normal, and need to increase the height to which the Y-axis can rise to.

PS: sorry to be a pest, but I just remembered another feature that would be wonderful to add - the ability to double, triple or even x 4 the same tube. As in, in this case, parallel dual 845's.

This option (defining voltage ranges I'll add in the next version of Simulator or rather in the Tube Optimizer).

J've just added KT88 in triode mode.

gsmok - I wonder if there is way for your app to use Dr. Reefman's pentode models without the data input file from the uTracer, like what Dmitry has done with the Koren pentode model and his Model Paint Tool app, where the user loads an image file from the datasheet and tries to match the model's curves with the image by adjusting the pentode parameters.

It is possible, but it interferes with my vision of this simulator. It might be worthwhile to do an independent script that will do this.
By the way. I found on your website information about Ayumi's tube models. I also read a thread on this topic in this Forum. Do you know of a place where this model is described in English? I know that it can be read from the Spice models, but I'd rather have them in the direct form.

Unfortunately, all his pages are in Japanese, I had to use Google Translator to read them. But all the codes are in English anyway, BTW, I think the Reefman pentode model is even more accurate than Ayumi's, so I am really looking forward to see what you can do with your app, which is already easier to use than R with pctube ;-)

According to the information that reached me I made a correction in the code allowing observation of the characteristics for small currents - less than 1mA - of course while maintaining the restriction that they are not less than 10% of the typical value (for example ECC83). As for the 10%, I wonder whether such restrictions to keep. There will always be someone who will want to see the characteristics for a 0.0999 of a typical current value 🙂.
I hope that Person who give me that request will be satisfied 🙂.

Thanks gsmok!!!

I'm comparing the el34, 6v6 and the 6l6gc...
The 6l6gc is giving good results...which is good as I have 4 of them with 2 in an unopened box.

Thanks again

Btw... I can't seem to find any triode curves for 6y6... it would be an interesting addition to your library...6y6's have a nice sound...I'm sure many would like to see it added.

I have added the possibility of parallel connection of tubes (up to 8 tubes). The number of tubes is defined together with ranges of calculation (text fields below the characteristics). This new option was associated with changes in the calculation, so please carefully check whether the simulator behaves properly !!!!.

Thanks so much, gsmok.

I just used x2 845's....I think maybe the red curve for wattage didn't recalc?

The graph should give results as if the x2 triodes were one double-size triode, no?

So, is the operating point parameters now giving totals for each value (which are then divided in half mentally when thinking of each tube, of course).

Very Best, Synchro27
