Hei.
im trying to reverse engineering this black box preamp driver for elac speaker.
Its has 8 pins and has a predriver circuit.
I been cutting it out and tried identify all transistors and resistors and one cap.
my problem now is that's something is wrong, i got a circuit board mounted temporarily on a pcb with the components, but it draws way too much current, and its humming a lot.....
there could not be a major error, but i attach the spice model, to see if someone can maybe identify some errors. ?
as you see, in the spice file, i have made the box and outside its the rest of the circuit.
best regards Niklas.
