Quoted from robm:Standup target does the same as the hole - ie: lights post but doesn't pop up. That stand up works fine in switch test.
Coil test will NOT fire the coil to pop post up, only grounding the Q12 TIP102. Also grounding pin 9 (that is the one that goes to Q12) of U3 does nothing.
Does this indicate U3 is cactus? Are the CA3081 chips available, or is there a substitute? I am in Australia so parts are not quite as common as US.
All those parts are common as in any Country, we have thousands of both in stock
