problema tda 1562

Recommended Posts

salut, am cumparat si eu un kit cu 1562 de la .... de pe Maica Domnului si l-am incercat. surpriza maaaaaaaaaaaaaaare! se aude fffffffffffffffffff prost. am scos schema de pe cablaj si am observat niste ciudatenii pe intrare. poa sa fie de la asa ceva? p.s. am luat si un filtru activ, l-am pus inaintea amplifului, dar la volum mare oscileaza. ajutor va rog.

ce ai desenat tu acolo e o schema clasica de preamplificator :axe: doar alea 2 condensatoare nepolarizate sunt in plus.. cum a zis si one fa-le un strap.... si pune un potentiometru de volum la intrare si nu o sa ami ai probleme, pentru ca banuiesc ca iei semnal de la calculator
