Hi tt3.hatrunglam

The flown-off IC seems to be a part of a flyback circuit, so it will return some day :slight_smile: . Could suggest something like UC2843, but cannot see the external switching device. Either it is on the bottom side, or the chip has an internal switch (somewhat rare in PDIP8 package). Any chance to have a photo of the bottom side?

Cheers,
heke

Given that, DK P/N 497-7694-5-ND would seem to be what you’re looking for.
