I think keep the existing terse help in LTspice... Add web links wherever necessary and clicking the web links will give examples, simulations and pictures, etc.. As new problems get solved they could

Just make it 500 meg or something larger...

No, grid will not get positive to cathode. Can I delete Rgk from the subcircuit? best regards Leo ...

This help idea sounds great. I drafted a request to 'Panama Mike' on this group, and copied that request to info@..., to copy and use scad3.pdf as a basis for a linkable, expanded help

I could work out mu and k for that tube-model. Unfortunately I could not get any value for Rgk of the tube. :-( Rgk is a problem .... best regards Leo

I would recommend using the level 2 switch model to create an ideal diode, as it often simulates better. You can even make the diode voltage 0. Some examples I have used: zero volt diode: .model

Hello Carl, I'm not sure whether this would rate as equivalent to the "Pick New

Hello, I think we will not have any chance to enhance the original help with tutorials. This help is intended to be a reference only. I am sure Mike will not change that. If we want a more tutorial

Thanx, yes that helps, it's possible to enter the parameters from the data-book ... best regards, Leo

Hello Lewis, Some of the spammers were ferocious in their persistence, weren't they? They seemed to have had a perplexing, particular interest in the section on transformers. Never understood that.

Maybe this will help.. "Spice Models for Vacuum Tube Amplifiers" AES, March 1995 http://users.ece.gatech.edu/mleach/papers/tubeamp/tubeamp.pdf Cheers A. Ganesan

LTwiki.org <http://ltwiki.org> is now fixed on the front page with a link on how to create an 'account'. This capability also exists if one tries to 'log in'. Sorry, I did not try to make it hard,

Hello Jim, I agree it should be easier to find help when one needs it. In your case how to create an account on LTwiki. But then once the account is created, the instructions how to do so become

dear friends, I need that model for noise matching. To ask here for the model or subckt is my last possibility. Perhaps s.o. has ... thanx, best regards Leo

Here is the correct way to link to files in Temp: http://tech.groups.yahoo.com/group/LTspice/files/%20Temp/Non_ideal_inductors.asc And your ideal transformer file:
