LTSpice tube models
Hi all friend here!.
I want to know if any of you have the following tube models or know where can I find them. In the Norman Kohen they aren't and Google didn't give any answer. They are: ECF801  EC900  EF184  EF183 Many Thanks to all. Best Regards.

Ok, thanks again!!. Do you know any model for pentagrid tubes? (for make a audio compressor/expander) such as a 6BE6,6CS6, ECH83? Hot to manage two input signals? And for a 6BN6??? (very difficult I believe)

I don't have any good ones for those tubes. Here's 6BE6 and 6CS6 models that use an opamp symbol. To use 3f4 in LTSpice you may have to change ^ to **.

Has anybody the model for 6gj7/ecf801?
Thank you.

Hi Osvaldo, try this in LTSpice. It has the 6HM5 model I posted in this thread. When you use the model be sure the name of the subckt matches the name/value of the component and the inc file you place on the schematic.
