Steve, I am not familiar with any of the board repair materials, so without any experience with them, I would go the safe route and add wires to whatever is left of the PC traces - scrape off the green solder mask to solder the wire onto the remaining trace or run full length point to point wiring - either should work fine. You have obviously destroyed the thru-plated holes, so be certain all components are connected - you may have to do the repairs to both sides of the board - fortunately with the PA transistors that should be easy to accomplish.
If you have damage to the collector or emitter pads, definitely use the wire to handle the current that must flow there - the conductive pen stuff may not handle much current. 73, Don W3FPR > -----Original Message----- > Due to my clumsiness in removing my blown finals I > have managed > to damage the PCB of my K2.
