3-500Z

The 3-500Z is a 500 watt dissipation triode with a mu of 130 designed for zero bias operation. The usable frequency for maximum ratings is 110 MHz. The first example was made by Eimac and the second Amperex. The third is the earlier version of the Eimac tubes and doesn't have the spacer on the pins.
