CLASSIC 100W HIFI DARLINGTON TRANSISTOR AMPLIFIER CIRCUIT Schematic Circuit Diagram
I say the classic, but many of the site we see similar darlington transistor quality hifi amphi circuit .. very few elements have been performed with few elements so clean sound account .. beautiful side all the details there are schema, PCB, material list, pictures information on the adjustment of the current flow, etc..
100W Amplifier circuit + -42v RMS 100W with symmetrical 2x42v power supply gives power to music power 140w but pay attention to your speaker at last sound 100w over 250w write down rms 20w etc … writer
Output transistors 1x ON709 and 1x BDX88C TO3 sheaths will be difficult to find these transistors use instead T8 NPN for BDW83C or TIP142 T9 PNP can be used for BDW84C or TIP147 correspond to transistors SOT-93 sheath use a larger cooler and heat conductor (thermal paste, Assemble the insulator using the insulator using cream etc etc ..)
Connect the ammeter between the T8 collollor and + feed for a rest current setting ayar P akım Adjust the 10k trimpot to the ammeter until you see 50m.
