Reflex klystron: specialized resonator/repeller ratings have no direct promoted columns and are preserved in TUBE_SECTION_PARAMETER; published maximum cathode current is promoted.

Source-dependent data

Operating conditions by source

Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
