I am trying to restore an old SuperTooth Disc/Blueant M1 Speaker. Works quite OK on plug pack, but now refuses to work on battery. Was working on new replacement batteries until recently. Used 2 ea new 4.8v 2,200mAh NIMH packs and they charge up OK, but fails to switch over to batteries when plug pack removed. It is NOT just a simple battery wiring problem as you can get ‘demo’ mode to work briefly some times, but does not change over! Need circuit diagram to pursue the SMD PCB and wiring. SuperTooth cannot supply circuit!!
Would appreciate it if anybody has a circuit diagram or partial schematic or any service information, they can post or email me as a JPG or PDF. jjb-oz, Sydney, Australia
