TThe Svetlana 4X150A/7034 is a compact radial beam tetrode. The 4X150A is intended for Class AB SSB linear RF amplifier service. It is intended for stationary and mobile equipment designs with power amplification at frequencies up to 500 MHz. The 4X150A has an indirectly- …

The 4CX150A beam tetrode is a close relative to the 4CX250B VHF/UHF RF power output valve and has the same finned anode structure. The silver plated fins are contained in an outer ring, and in use air would be forced over the fins for anode cooling. A special base and chimney were designed for the purpose.

Because of the all ceramic/metal construction and brazed anode cooler, the maximum rated plate dissipation power of the Svetlana 4X150A/7034 is 250 watts. This rating may be exceeded for brief periods during circuit adjustment without damage to the tube.

2019年12月14日 · The 4CX150 and 4CX250 were used extensively by the US Navy in the pacific. AM, AME, FSK RTTY, Single Sideband Voice, etc. They were linear enough to use there. Not very pretty. 4CX150 is good for UHF, so needed to be built in a double box, with the screen connection right at the wall between one box to the other box. Needs an odd socket.

2025年1月13日 · You should be able to make the 4CX150 work at lower voltage, but only at low power. Just ground the plate, and use the Screen as if it was a 12 Watt dissipation Plate.
