Tensiune anodica reglabila

Recommended Posts

Cred ca in Tehnium de prin anii '80, era o schema de sursa de tensiune anodica reglabila, 80-300 V / max. 100 mA pentru diverse experimentari. Era cu 6p3c sau alta pentoda de putere. Ma poate ajuta cineva cu o astfel de schema sau asemanatoare ? Multumesc frumos.

La asta ma refeream. Ai experimentat-o ? Daca esti multumit, nu mai caut altceva. Vroiam mai multe variante pe lampi, sa am de unde alege.

Nu, n-am lucrat cu ea, nu știu cât de bună e.

Doar am căutat-o ptr. tine.

Faci cum doresti. Pt. mine, acea schema da curent foarte mic si in plus, este nestabilizata.Spor

O folosesc doar pentru experimente de scurta durata. Stabilizarea este un moft pt ce-mi trebuie mie.
