prezentare amplificator de laborator


Recommended Posts

Amplificator realizat manual cu hibrizi de la PHILIPS. L am ascultat și sincer sa fiu n am rămas impresionat de putere și dinamică, fapt pentru care mi a trecut prin cap sa-i schimb etajul final cu kit-uri de la TDA , unele de 100w.
Credeți as greși făcând acest pas? Carcasa îmi place foarte mult cum este realizata, da impresia unui instrument de laborator, e clar ca cineva a muncit mult pentru a-l construi.

Da, ar fi o mare greseala.  Din mai multe motive.

1 - datorita tehnologiilor constructive, integratele hibride (cel putin unele din cele originale) suna ferm mai bine decat integratele de putere "clasice".

2 - amplificatorul a fost conceput si construit ca un intreg, este cel putin incerta posibilitatea inlocuirii directe a etajului final cu doua kituri cu TDA-uri.

3 - din tot ceea ce ati scris rerzulta clar ca nu aveti nici macar o minima expertiza tehnica care sa va permita o asemenea interventie. Poate doar daca va gandeati sa va faca lucrarea un electronist priceput.
