Modele tuburi electronice

[Patefon]

Va propun sa adunam modele pentru simularea circuitelor electronice cu tuburi. 

 

Am sa incep prin a va prezenta un model pentru pentoda 6J4P atat in conexiune trioda cat si in conexiune pentoda. Prin bunavointa lui @jj101, caruia ii multumesc foarte mult, am avut masuratorile facute pe lampita mentionata pentru conexiunea ca trioda si in regim de pentoda cu grila 2 la 50, 100 si 150V. Iata ce a iesit:

 

 

Important pentru modele generate este convergenta modelului de pentoda la modelul de trioda atunci cand e legata ca atare:

 

apoi sa comparam rezultatele cu graficele din datasheet:

 

Si iata si modelele generate:

Acum o sa va rog sa ma ajutati putin cu distribuirea capacitatilor. In datasheet sunt definite 3 capacitati:

dar modelul de pentoda imi cere 5. Care cum le impart?

[Patefon]

Cred ca nu va pot ajuta acum. O sa pot cand voi termina uTracerul. Pana atunci... rabdare.

[Patefon]

Am avut nevoie de un model pentru 6N3P si ce am gasit pe net nu prea a potrivit cu datasheet-ul. Asa ca inarmat cu rabdare am folosit un programel cu licenta publica (Engauge Digitizer) pentru a extrage graficele din datasheet in format numeric. Cu datele extrase am potrivit punctele culese intr-un fisier cu sintaxa lui miutracer (ca si cand ar fi fost masurate cu aparatul respectiv) si am pornit la cautarea unui model. Iata ce a iesit (ATENTIE - date din datasheet):

Nu uitati sa adaugati capacitatile de manuta in interiorul modelului.

 

 

P.S. - Cum impart si eu capacitatile la pentoda 6J4P ??? 

[Patefon]

Daca tot a venit domnul Lazaroiu cu ideea de a vedea cum se compora in audio lampa numia RS1003 (vezi mesajul de aici http://www.elforum.info/topic/54841-simulari-scheme-cu-tuburi-electronice/?p=1174056 ) m-am gandit sa fac un model pentru ea. Iata rezultatul:

Evident nu am avut timp sa caut prin datasheet capacitatile aferente. Se va completa de catre fiecare doritor in parte.
