I have an Atilla the Hun that works but the pop and sling solenoids are very sluggish, often responding to a switch hit after the ball is gone. I've cleaned up the crappy caps on the main board and rebuilt the pops to no avail. Any thoughts?

Thanks for the reply!

All the playfield solenoids other than the flippers (two slings and three pops in this game) are slow to respond but they're not consistent. Sometimes a sling will fire with okay power and in time to redirect the ball, and other times it's very late. I haven't noticed if the drop target resets are slow but that would be more difficult to tell I think. If I run the switch test, all the switches register but I'll try and see if I can spot any delay between a switch closure and the scoring on any of the regular feature switches.

There was a small amount of battery leakage on this board in the past but nothing that appears to have seriously compromised traces. It's quite minor compared to most acid damage I've seen over the years. The IC socket for the chip right beneath the battery mount does look a bit suspect though, so I can clean that up—might even have a spare holder. Not sure which chip that is or what it's for though.
