Ich hatte etwas Zeit, ein Modell einer Triode auf meinen Simulator zu adaptieren. Interessant an diesem Simulationsmodell ist die Möglichkeit, jede Triode anhand von 14 Parametern zu beschreiben.
Wer kann mir helfen, für eine gegebene Röhre diese Parameter aus den Datenblättern zu ermitteln:
*
* THE TRIODE'S 14 PARAMETERS ARE:
*
* SFS shape factor of the saturation law.
* VBIG contact potential of the grid
* (the voltage above which grid may current start to flow).
* VBIA contact potential of the anode.
* MU amplification factor at slighly negative grid voltage.
* RMU reduction factor for MU at very negative grid voltage.
* VMU grid voltage for mid-range MU (negative).
* SFMU shape factor for MU reduction law.
* K perveance at slightly negative grid voltage.
* RK perveance reduction factor at very negative grid voltage.
* VK grid voltage for mid-range perveance (negative).
* SFK shape factor for perveance reduction law.
* SIGMAG effective cross-section of the grid relative to the anode.
* ALPHAG grid current amplification factor.
* SFG shape factor of the grid current law.
Das wäre die Liste, noch 2 Bilder von ermittelten statischen Kennlinien
In der Anlage das Modell als subcircuit. Die Endung muss bei meinem Simulator .ckt sein. Es ist ein reines Textfile

| You reach this tube or valve page from a search
after clicking the "tubes" tab or by clicking a tube
on a radio model page. You will find thousands
of tubes or valves with interesting links. You
even can look up radio models with a certain tube
line up.
