The CCS is biased at 6 amps?...
But, some like it hot ...
davidallancole said:Not quite. In the simulation it draws 1.8 A. It puts 12 volts out nicely into 8 ohms, with a 1 V input.
0,6 Volts (one diode drop ) across 0,1 Ohms is 6 Amps...me thinks...
davidallancole said:You must have not noticed the 2.5k resistor after the diodes reducing the current.
That way your CCS is not thermally stable.
Why not simply , to use a 0,3 Ohms emitter resistor..
davidallancole said:I built a rough one of these at work two weeks ago. That 2.5k resistor I used was a pot so I could adjust the bias current. The transistors are on some pretty big heatsinks. They barely come above room temperature.
That's ok! ...
