4X150D RADIAL-BEAM POWER TETRODE The Eimac 4X150A and 4X150D are compact power tuba for use as amplifiers, oscillators, or frequency multipliers at frequenciœ up to 500 mega- cycles. The 4X150A is to operate with a heater voltage of 6.0 volts, whereas the 4X150D is designed for operation at a heater potential of 26.5 volts. Otherwise,

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- …

Feb 9, 2025 · The 4X150D is the 26.5 volt filament version of the 4X150A, which uses 6.0 volts. All specs are the same and it uses the same SK-600 socket. Comes from a box (estate) of tubes.

The 7034/4X150A and 7035/4X150D are forced-air cooled, extemal- anode radial-beam tetrodes with a maximum plate dissipation rating of 250 watts and a maximum input-power rating Of 500 watts up to 150 MHz, with

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.
