My generic LTspice models for vacuum tubes

Mein Essay

My essay

Unter diesem Link findest du mein Essay (40 Seiten) zu meinen generischen Röhrenmodellen. Sie stellen die Fusion der besten Ansätze dar, die ich mittels intensiver Webrecherche gefunden habe. Die wichtigsten Vorteile:
1) Mein Diodenmodell berücksichtigt den Anlaufstrom, mit sanftem Übergang zum Stromverlauf nach Langmuir-Childs Gesetz.
2) Mein Triodenmodell verwendet für das Gitter mein Diodenmodell und bietet für positive Gitterspannung unerreichte Genauigkeit des Gitter- und Anodenstromes!

3) Mein Tetroden/Pentodenmodell ist eine Erweiterung meines Triodenmodells. Daher liefern meine Pentodenmodelle, wenn als Triode geschaltet, immer noch korrekte Ergebnisse.

Viel Spass beim Lesen meiner Doku!


Under this link , you will find my essay(40 pages) about my generic vacuum tube spice models. They represent the merge of the very best approaches found in the web. Key Features:

1) My Diode model considers the "Anlauf" current, with a smooth transition to the current according Langmuir-Childs law.

2) My Triode model uses for the grid my diode model and provides for positive grid voltages an unrivaled grid & anode current accuracy!

3) My tetrode/pentode model is an enhancement of my triode model. Hence, it delivers also correct values when it is triode connected.

Enjoy reading my paper!

This model is quite accurate up to Vg=4V and offers usable accuracy up to Vg=16V.

7963 (Sylvania Submini Twin Triode, strap grid)

811A (RCA power triode, direct heated)

8808 (RCA Nuvistor triode, high gm, ultra low noise, copes GHz, class C capable)

ECC81 (Philips Twin Triode)

ECC81.RFi4 (RFT Twin Triode)

ECC86 (Zaerix Low Voltage Twin Triode)

EL34.TEi4p (Telefunken Power Pentode)

Due to lack of iG1 data, this tube model is "preliminary", as its iG1 model is guessed by comparison with iG1 parameters of similar tubes (6BW6 and 6L6GC). It is assumed that by this methode, an error less than a factor 2 between iG1 model and reality is acheived.
