| Descrizione |
The HK-304H is a 300 watt general purpose triode with a mu of 20 made by paralleling four 75 watt tubes in one envelope. Although they have the same military number as the EIMAC 304TH they differ in the height of the tube so they are not always switchable. All the grid connections came through the glass and were terminated with a metal ring and grid cap. Some had two grid caps. HK also made this tube in the lower mu version the HK-304L .
