Phototube has no dedicated canonical SectionType; applicable published electrical ratings/characteristics are promoted where schema fields exist and other data are preserved in TUBE_SECTION_PARAMETER.

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.
