NATO Eimac 8877 Milspec Triode: This is a milspec Eimac 8877 ceramic triode, NATO# V06-0001-000 5960-00-313-6715 sh:2921
It fits perfectly into any 8877 socket since the OD is identical to consumer grade Eimac 8877. But the inner heatsink is 2X the surface area of Eimac consumer, and the heatsink metal itself is 50% thicker than Eimac consumer.
It has been tested to legal limit power which it achieves easily. But it’s clear from looking at its physical characteristics that NATO wanted and got an 8877 that could be pushed harder, for longer, and in more extreme conditions.
The tube has been tested (anode characteristics consistent with being clipped into a rig for testing), but otherwise it appears to be in unused or very lightly used condition. Comes in original packing materials.
