Request for help on a B&K Precision 1652 Power supply.
« on: October 16, 2017, 10:56:19 am »
Hello All,

Request the forum members for help with my B&K Precision 1652 Power supply.

The B&K Precision 1652 Power supply I got off Ebay has a part of the main PCB heavily charred
near R55 and R56 so much so that I cannot make out the trace connections on the top or bottom side.
Also the internals seem to have been heavily modified by someone and I was left wondering if this mods were done at
the factory or during the repair attempt of the previous owner.

If anyone on the forum has this power supply model, could I request few pics of the area near R55 / R56 (both top and bottom sides)
so that I can rewire the traces?
Also a pic of the whole main board would be helpful to determine if the mods I had mentioned were actually part of the factory installation?

best regards
