Receptor performant si simplu cu tuburi

Recommended Posts

6DS4 este echivalentul lui 6CW4 dar cu panta variabila , iar 6CW4 are ca echivalent nuvistorul american 7586 sau sovietic 6S51N sau 6S52N .

Probabil ca un compromis acceptabil ar putea fi folosirea in intrare a unui ECC 189 / PCC189 care contine doua triode din care una cu panta variabila , iar trioda cu panta variabila in locul lui 6DS4 .

Sau se justifica modificarea intrarii si VFO + mixer eventual FI + AGC + Smetru conform schemei de mai jos , dar totusi........nuvistorul in intrare este perfectiunea .

Evident filtrul cu quart de 9 MHz este XF9B ( fara echivalent...... ) .
