hi, I've been thinking about using some current output DAC with dynahi, this design is simple, current from the DAC's outputs (balanced) is injected to the emmiters of the input transistors T5, T6, this point is kept on ground potencial using T3, T4.. T1, T2, LED1, LED2 and R1, R6 are current source and current sink, servo point works exactly like in kevin's amps, balancing the voltage of the midpoint between the LEDs changes current flowing throuh them and this affects voltage across them.. OUT_A and OUT_B should behave exactly like correspondings points of the input stage in kevin's amps..
might this actually work? and why not
thanks!
