Fixed a pair of LA3A's for a client a few weeks ago. They heard them and they sounded great. Since then They brought it back to me saying the unit is now noisy. This is true. I hear a hiss on both units that was not there before. If I play with the gain knob the hiss will increase as I bring the gain knob up. I am not 100% familiar with the la3a's and I know a few of you guys are. So might as well ask what are potential reasons this could be happening? This sounds exactly like when you have an amp cranked too loud and you get that SSSSSSHHHHHHHHHH. in the background.
