Power - Beam (NOT sweep) ·BeamPower
Compact conduction-cooled high-perveance radial-beam tetrode, electrically related to the 4CX250R and ruggedized for severe shock and vibration.
The 4CS250R is a compact conduction-cooled high-perveance radial-beam tetrode, electrically identical to the 4CX250R except for its thermally limited dissipation system, and ruggedized for shock and vibration.
General specifications
Properties common to every published source and operating point.
Electrical assignments shared by every tube using this base designation.
No verified pinout is recorded for this base designation.
1 physical section, each with unique specifications.
Section 1
Source explicitly states plate dissipation is limited by maximum anode and ceramic/metal seal temperatures; no single plate-dissipation maximum is promoted.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
