Motorola FM900 Power supply

Posted by Mike M on 06/20/2007 12:14

:Hello All, : I have an FM900 but I see an external power supply went with it. It's missing. So I may have to build one. Does anyone have the schematic for the Motorola FM900? I know it uses a 2N176. I have a few of those. I see three devices that look like transformers but probably one is a filter choke. This is a vibrator-less switching power supply. : :Thanks, : :Dave
