alvin1118 0 Report post Posted July 15, 2008 Received my LM4562MA, removed the AD8397. OMG, 2 PCB track came out got to use tiny little jumper to solder the LM4562MA on the PCB. Luckily, my Mini3 still works well AMB Mini3 with LM4562MA, current rating 15mA, which means 170mAh battery can last about 10hrs It sounds very detailed, a bit too detailed and cause harshness in high.. great for monitoring purposes instead of easy listening Share this post Link to post Share on other sites
