Recommended Posts

Cum vii se pare ce vreau eu sa fac aici? mai jos sunt in oridine schemele pentru un amplificator audio :

 

Mixerulhttp://tinypic.com/usermedia.php?uo=adkBqYNLlttrxoAghIlUh4h4l5k2TGxc#.U6rBj5SSyNI

 

Elementele lui componente:

P1 = 5K P2 = 5K P3 = 5K R1 = 180K R2 = 2M2 R3 = 750R R4 = 1K R5 = 15K
R6 = 220R R7 = 1.5K R8 = 820R R9 = 150R R10 = 100K R11 = 180K R12 = 2,2 M
R13 = 750R R14 = 1K R15 = 180K R16 = 2M2 R17 = 750R R18 = 1K C1 = 1µF-63V
C2 = 100µF-25V C3 = 220µF-25V C4 = 100µF-25V C5 = 220µF-25V C6 = 1µF-63V
C7 = 100µF-25V C8 = 1µF-63V C9 = 100µF-25V Q1 = BC550C Q2 = BC547 Q3 = BC557
Q4 = BC550C Q5 = BC550C B1 = 9V J1, J2, J3 = 3mm Mono Jack SW1, 2,3,4 = Comutare SPST

 

Corectorul de ton cu preamplificator de 750mw: http://tinypic.com/usermedia.php?uo=adkBqYNLlts7A8cySqG9GYh4l5k2TGxc#.U6rB3ZSSyNI

 

Etajul final: http://tinypic.com/usermedia.php?uo=adkBqYNLltvYKk1UdGCU3oh4l5k2TGxc#.U6rCLpSSyNI 

 

Iar aici  etajului  final ii  modific cele doua rezistente din amplificarea globala R1=150k si R2=4,7k conform alimentarii de 22v nesimetric sa reziste Tda-ul la intrare  la aproximativ 750mV care ii furnizeaza corectorul cu preampliful din schema de mai sus, R1 fiind 75k iar R2 4,7k.Se potriveste ce vreau eu sa fac aici , schemele si ordinea?
