Identify the primary inputs with an ohmmeter from the fairly obvious 2 sides of the line inside the chassis. Then apply power, and you will be able to find the outputs and their polarity. On the flatpacks I’ve examined you could fabricate the input connector from copper-clad FR-4, and make the output connections with 1/16” copper, held in correct spacing with unclad FR-4.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>__________________<o:p></o:p></p><p class=MsoNormal>Clyde Washburn, K2UE<o:p></o:p></p><p class=MsoNormal>k2ue@ieee.org<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
