6P3S in clasa AB2

Unread post by DanMinciu » Mon Sep 02, 2019 10:00 am

Dupa cum am scris la preamplificatoare, as vrea sa fac o clona a Conrad-Johnson MV45.
As vrea doar. Pentru ca mie-mi plac 6P3S-E... Si atunci am cautat, am intrebat...si am ajuns la concluzia ca 45W cu 6P3S se poate obtine in clasa AB2... Si daca tot ma sucesc, hai sa ma sucesc la 6P3S fara E.
Schema include 2x 6N3P, 2x6N6P si 4x6P3S.
Am vazut-o propusa de dl. Valderama pe un alt forum:

E drept ca nu am ambele 6N3P, doar una. Deci 6N3P=>6N1P si modific etajul de intrare si defazorul.

Si am modificat etajul de intrare si defazor: am schimbat 6N3P cu 6N1P.

O sugestie de modificare (sau viceversa: tai partea de jos ...) + mai ai un fir nerutat

Daaa... După ce mi-ai arătat, am văzut-o... Iar firul ne rutat îl voi "ruta" cu o sârmă... :). Mersi de observație
