I thought it might be something like that.

A word of warning - be careful when paralleling these devices. Add a small resistor to the gate of each SCR. This will prevent the gates from "ringing". Gate ringing destroyed my friend's coil gun that used SCRs. To over simplify, gate ringing causes the SCRs to turn on and off very very rapidly.

Also, I'm not sure if you need to add a ballast resistance to spread the current over multiple devices. Can someone verify this?
