Hi, thanks so much for helping me solving the problem.. But both solution (adding Roff and changing the ground position) are giving different results. So I wonder which one should I use. Also Tony,

I didn't know Helmut was Italian! Thanks.

Helmut bottom posts, and it's his group. In Rome, shouldn't we do what the Romans do? -- JF

Ok, that was a good thing to learn... Thanks everyone! /Johan

LTspice is not intended as a parametric search for all possible diodes. You setup your schematic, choose the approriate parts and put them into LTspice. LTspice is only for simulating an existent

Thanx John, I will spend the rest of this day with searching the lib .lib ararchnid.mod. I think the best is to search in www3. best regards ...

Yes, GaN FETs are perhaps godd for that. I've thought about that. They are good, if they have a large input resistance and low input capacity. I will check that. best regards ...

Hello Leo, To my mind the ideal device for your circuit is the old VMP4 - a first generation VMOSFET from Siliconix from about 25years ago. These devices had a remarkable combination of properties,

Tube life is related more to the temperature of their envelope, if the heater is reliably constructed. http://members.shaw.ca/legg/2000a.html I'm not sure that you can assume a more reliable tube

Hi folks, my LTspice-version has problems with that circuit :-) help! best regards Leo ...

<snip> </snip> Hello Carsten, 1. The MN prefix tells SPICE that the device is an N-channel MOSFET. 2. An intrinsic device is a fancy name for a circuit element that is built in to the SPICE code.
