Citronic Digi 16P mixer amp maybe 2007
Hopefull ps bad/burnt solder on a 2W ceramic resistor , double sided board
and soldering, or not from the reverse side, the trace on the blind side, as obscured by the resistor. Anyone know of the SWPS schematic or is Citronic rebadged as other names? The SMPS controller (seems to be outputs via a few predriver TO92 to 2x TOP3 powerFETs across the rectified mains) a SMD IR2156S which according to the datasheet is a flourescent tube electronic ballast and igniter, no mention of use as a SMPS, with obviously no igniter requirement one hopes. Anyone come across such as this before? |
