I'd love to see how its wired. I wanted to do the same thing to a few games using 1 rectifier. I have an EM Cleopatra with the DC pops and flippers and its a lot more reactive. For the flippers, they use A-17875 and the pops are A-1496. May try those coils?

Edit*** Not sure if they will fit, on the back of the manual it lists new items appearing in this game and has new coil mounting bracket and stops for the flipper and pop bumper coils. I think the coil stops are different for DC coils?

Quoted from davidr415:

Here is the circuit that is used..
I tried several things... tried converting back to AC.. too slow. I didn't like the way it played. I tried de-tuning the pops by moving the EOS switch closer to the playfield, thus reducing the duration of the DC pulse to the pop solenoid. This helped reduce the strength of the pops, but I still got machinegunning occasionally. Ultimately, I installed slightly bigger rubbers adjacent to the pops and this seems to have done the trick.
I didn't have any higher resistance coils to try.. this may have worked.

Thanks for doing that.. Its a pretty basic circuit. I'm going to give it a shot on something here when I get a chance..
