Thank you. It was imported and saved in a text editor on a Mac and which saves as an rtf file. So I need to find an editor that saves in .txt instead of .rtf
The imported model for the MJL21194 and which I have checked the file to see if there are any “\cb1” characters in.
This is the file text:

Hi there,
I am trying to run a simulation in LTSpice of the circuit below but it keeps coming up with an error as in the image below.
Can anyone suggest what "\cb1" refers to? There is nothing in the imported transistor model to account for it.
Thanks
Julian
Hi all,
I'm exploring LTSpice and am trying to find out how to add a transistor that is not in its immediate NPN model library.
Specifically, I'm looking for a model for the MJL21194 that I can somehow add to the Spice library.
Any ideas on where to get a good model for this one?
Thanks
Hi all,
Over the last week or so I have been working on calibrating the updated potential divider that uses 100k resistors and includes a cap trimmer for probe compensation (Pic 1).
Early tests using DC and square wave calibration waveforms and voltages were helpful in setting the compensation...
Hi Brian,
Yes I will certainly try just using the relay and no FETs.
The reason for having a swapper at all is so that the battery providing all the power is not being pulsed at the same time with the HV spikes or, in due course, the high current capacitor discharges. The one being pulsed is...
Interesting- from what you say I should either reduce the voltage to the Gate, say to 6V, so that Vgs is significantly greater than the Vgs (th) or do without the FETs altogether. When I considered the latter some years ago I thought that the small relay was not up to switching 2A securely.
I...
I’m not claiming anything yet till I’ve done my testing but I take your point. I need the swap fets to act like a simple switch, letting through the battery voltage when triggered by the relay. The typical current demand is about 2A max. Yes I loose 1-2 V but that’s not important here.
I note...
