GENERAL DESCRIPTION |
The 4CX300A is a compact power tetrode having a maximum plate-dissipation rating of 300 watts. The ceramic/metal construction and the internally unitized electrode structure combine to make the 4CX300A especially durable and free from mechanically induced noise under conditions of severe acceleration caused by shock or vibration. |
