No Nino the UL hasn't worked since I dug the game out of a machinery shed a couple of months back where it had been for about 4 years with a chaff bag chucked over it
. I've only just started to attack the issues. I put the faulty flip board into Corvette and the UL flipper doesn't work there either so I'm prety sure it's isolated to the board.Until I soldered in the TIP36 and predrivers the board looked untouched. Maybe it is that R23 resistor as it seems to have the odd reading out compared to the others and the schematic specs
