Hi, it looks like you replaced 7912. If you replace 7812 and 7912 with a full mold package, the insulation sheet will be permanently unnecessary. Generally, tantalum capacitors (Blue Grim Reaper) short out, so you should replace them with capacitors of similar capacity. Either the power fails or the Blue Grim Reaper explodes. Good luck.
excellent edu
