The full resolution image can be downloaded by clicking the image above. (it opens in a new window so you may need to disable pop-up blockers) I have the componet values for most componets but some were experimental so I have to find them. I will post a table of values for the componets when I have them all. Capacitors without polarity indication are non-electrolytic. I think there are 76 componets total, and this circuit does not include the capacitor charge meters.
| Componet |
Description |
| B1 | 500V Bridge rectifier, current is low duty cylce, so 1 amp is probably fine. |
| B2 | 50V Bridge rectifier again at least 1 amp. |
| S1 | main power rocker switch (you may want something where you can easyily tell if it is on or off. |
| S2 | momentary contact switch, bank one charge |
| S3 | momentary contact switch bank two charge |
| S4 | momentary contact switch bank three charge |
| S5 | Main Firing trigger momentary contact |
| S6 |
Bank 2 manual fire momentary contact |
| S7 |
Bank 3 manual fire momentary contact |
| S8 | Bank 2 saftey SPST |
| S9 | Bank 3 saftey SPST |

| L1 | First coil, the less resistance the more current, we used #10 flattened magnet wire. < 1 ohm |
| L2 | Second Coil we used #14 wire 2-3 ohms |
| L3 | Third Coil we used #14 wire 2-3 ohms |
| D1 | Reverse current diode, we found that you usually need ridiculously high current rectifier diodes. This stops the collapsing magnetic field from destorying the SCR |
| D2 | Reverse current diode, we found that you usually need ridiculously high current rectifier diodes. This stops the collapsing magnetic field from destorying the SCR |
| D3 | Reverse current diode, we found that you usually need ridiculously high current rectifier diodes. This stops the collapsing magnetic field from destorying the SCR |

| D8 | LED for the break beam; the brighter the better however almost any LED will work |
| D9 | LED for the break beam; the brighter the better however almost any LED will work |
| T1 | 1:2 transformer, that's right it is a step up! |
