| Part | Part Number | Qty. | Notes |
|---|---|---|---|
| Push button | KM2-1 | 1 | Different button can be used, but PCB footprint must be updated |
| Toggle switch | MT-1 | 4 | Different switch can be used, but PCB footprint must be updated |
| Tube Socket | GD-PARTS B7G | 24 | |
| Vacuum Tube | 6AU6 | 24 | Other tubes may work, such as 6CB6, but not guaranteed |
| VFD | IV-26 | 1 | COther VFDs may work, but footprint and resistor values will need to be adjusted |
| Resistor | 100 | 26 | |
| 330 (5W) | 1 | 3W will be fine, but I like overkill | |
| 1k | 2 | ||
| 33k | 22 | ||
| 47k | 7 | These are the 7 resistors for the VFD | |
| 220k | 53 | ||
| 1M | 4 | ||
| Schottky Diode | SD103 | 37 | Any diode with more than 30V reverse protection will work |
| Capacitor | 102 / 1nF | 1 | Larger capacitor size will provide better debouncing at expense of speed |
| Pin Header | 90-degree male | 2 | Any type of header to fit your needs can be used here |
