I just spent the day trying to design an audio amplifier with 1000 volts per volt gain, and though I realize this requires some stabalization, I am thoroughly frustrated. I had transistors that were intermittantly operable, op amps that worked in weird ways, and I could "fix" things by pushing parts around. I think breadboards are overrated. But it could be that my 25 year old board is a dead soldier. I've pushed big leads into tiny holes, I've burned stuff here and there. The board is full of battle scars. Nevertheless, I think I'm done with them.
