Hi, I have drawn this Tube amplifier schematic in LTSpiceXVII and I don't have the knowledge to add ,subckt files to download or implement. I think LTSpice should have built in standard models built in console, that you could edit to your specific parameters in fields from a pull down menu. That way, you would not have to mess with basic programming skills, like pascal or basic. Can someone run this schematic for me with results would be appreciated! Thanks
Your sch is incomplete..no return ground for PSU?
Depend on the version, you may need to include the full path of the inc file.
See attachment and results.

This is a SE Tube Amplifier that is Triode wired EL34/6CA7 and if using TubeCad, the voltage drop across the Edcor GXSE-15-8-2.5K IS ABOUT 35VDC. So the plate would see about 300VDC. Thanks for the results, as the voltage out swing is actually very good. The Vth= about 8.74 which a higher number is best. This should be a good sounding amplifier. Triode wired = 3-watts / UL wired = 6 watts, Max. My tube pre is around 22db output of gain and will drive this amplifier very well, as with my very sensitive Audio Nirvana 10" CF full range drivers in ported enclosures, will fill my small 22'x14' Living room. Thanks for your help! If anyone can contribute anything else is welcome to download this schematic in their LTSPICEXVII and manipulate as you wish. I just need a print out of results in sheet form showing some more actual measurements in frequency axis and impedence/Transfer function and Damping factor, that I do not know right now... Thanks to all of your efforts!
