Th3_uN1Qu3 Posted December 15, 2009 Share Posted December 15, 2009 LM12 e operational de putere nu tranzistor. Adica circuit integrat se cheama, si nu are 150W ci 80W reali. Daca nu'l gasesti nu prea ai cu ce sa'l inlocuiesti, incearca un amplif cu eternul si fascinantul TDA7294. Schema cred ca asta vroia sa fie: http://electroschematics.com/10/lm12-15 ... amplifier/ Link to comment Share on other sites More sharing options...
remus68 Posted December 15, 2009 Share Posted December 15, 2009 O schema asemanatoare, dar cu TDA2050 iti ofera maxim 50W/4 ohmi la +/-22V, dar e bine sa utilizezi difuzoare cu impedanta de 8 ohmi.http://diyaudioprojects.com/Chip/DIY-TD ... Amplifier/ TDA2050 se gaseste foarte usor. Link to comment Share on other sites More sharing options...
