oh WOW!!! Audioguru you made me excited!!!
this schematic is really simple and i think i can understand it all
of it without your help, so here i start!
0,47uF is a coupling capacitor for cutting any DC and for not letting
any resistive loads interfere with the bias of the Q3 transistors.
27K is a the resistor to bias Q3
390K is the negative feedback resistor
Q3 is the pre amplfication stage (voltage amplification)
the diodes i don't know exactly what they are doing there
The R2 regulates the emitter/collector voltage
Q4/Q5 is the final stage... two transistors in push/pull which each one
of them handle half period negative or positive.
470uF is an output capacitor to remove DC offset...(but probably destroys the frequency responce?)
guys is that simple to understand an amplifier with descrete components?!
if yes why some schematics i have seen are huge?
I want to know some more classes other than AB... btw the schematic
i uploaded it's more difficult for me, i don't understand it.... so how am i understand more difficult schematics?
thank Audioguru!!! you're great!!! (i also thank the other guys too...)
