I have a Serenade and have not been able to find schematics and it looks like some of the game elements are similar to these other machines. I am hoping it can help me get the last issues worked out. Thanks much!

I might... I was in the same position as you, since I was restoring a Serenade for a client without schematic; I acquired a similar United machine's schematic... let me see what I've got.

Can't locate my copy, sorry.

Thanks for checking! Most everything is working as it should on the machine but there are a few things that don't always work right. I suspect the replacement coils are not the right resistance.

If you have the original coils, you can measure ohms on the coils with an ohm-meter; easy to do with the coils out of the game.
Also, some United coil resistance values listed here:
