im nik from milan italy, nice to enter in this comunity of pinball.
I read this old topic:
and i think i have same problem.
Power supply card of my gottlieb counterforce system 80, have led 5v and 12v power on.
But if i check cable there are not 12v and 5v but less.
Tp3 w/ tp4 +5v is 2.4v
Tp3 w/ tp5 +8v is 5.6v
What do u think? is good idea to replace C1 (the 6800uf cap), or is
better before to check others? is good to check bridge and how i can check it?
Suggestion where to buy c1?
thank a lot from italy for your help!
Note: in photo sound card in disconnected, because probably have some defect (connect 5v led dont work), but i will think after have resolved problem of 12v/5v...
