4CX400A Radial Beam Power Tetrode 3/98 he Svetlana 4CX400A is a compact, high-perveance radial beam tetrode having a plate dissipation rating of 400 Watts. Because of the unique internal geometry of the Svetlana 4CX400A, the tube will operate at low plate voltage with high efficiency.

One that caught my eye was the 4CX400A (400 Watts plate dissipation). A closer look revealed it had possibilities as a drop-in upgrade to the Eimac 8930 (250 Watts plate dissipation). We'll examine this upgrade to two popular VHF amplifiers, ARCOS (W2GN) 2 Meter Kilowatt, and the Fair Radio/FAA surplus AM-6155/GRT-22 222 MHz linear amplifier.
