The P8079HP is a three-stage cascade inverted first generation image intensifier tube with a P20 phosphor screen and integrated power supply, It requires a voltage of 6.75V, though operational performance is maintained until 4.5V.
Although very large (196mm length, 70mm diameter), and with a strong pincushion effect in the output image, due to the three cascading stages the performance is comparable to later generation image intensifiers.
| Performance Parameter | Unit of measurement | Value |

| Resolution | lp / mm | ~40 |
| Photocathode Sensitivity | uA/lm @ 2856K | ~300 |
| Phosphor | P20 | |
| Screen Diameter | mm | 25 |
EP-16
A Soviet/Russian copy of this tube called EP-16 exists. All known examples are made by MELZ.[2] This tube is used in 1PN54.
