Hi,
I am often repairing solid-state audio amplifiers, and would like to build some kind of current limiting circuit.
Ideal would be some "black box" similar to limiting current with a light bulb, because it would be great if it didn't need a ground connection.
Is that possible?
If not, could someone help me design a current limiter, which won't be too sensitive to input voltage variation?
Another thing that concerns me is, that if I use some current limiting devices on both power rails, is it possible that the two limiters would fight against each other or oscillate?
Many thanks
