Over 100 Transformers

Transformers Can be
     User Defined

Output Transformers
The output transformer can be selected or user defined from the drop-down list or from the transformer dialog box, which is accessible from the "Tools" heading on the menu bar or the right mouse button speed menu.

Output Tubes
The list of tubes that are known to SE Amp CAD can be brought up by clicking "Tools" on the menu bar and then clicking  "Tube  List." After checking one of the tube type choice eyelets, pressing the up and down arrow keys will move the selected tube up and down the list, which allows the user to compare quickly the characteristics of all the triodes available. (Some tubes differ in name and shape of envelope, but not in essential electrical characteristics, 6080 and 6AS7 for example) The values displayed have been culled from various sources: old tube manuals, current product specification sheets, and tube related web sites.

Over 30 Tube Types

Because the mathematical modeling of a triode is both complex and involved, user defined tubes cannot be added. If you have a tube you want to see added to the list, drop us a line and we will see if we cannot add it to a future release (if you can send actual curve traces of the tube, all the better, as tube manual graphs are very suspect. Contrary to public opinion these graphs are not always derived from a curve tracer (20 points of data and a French curve worked just fine for many tube companies.)
