Eimac 7580W / 4CX250R: Offering this from recent estate tube lot - cosmetics indicate either NOS or very, very low hours.
The 4CX250R/7580W is the heavy-duty, ruggedized version. Like the 4CX250B, it has 6.3v filament voltage. They ( “typically” ) deliver more output in most linear amplifiers which use the 4CX250B.
My TV-3B/U tube tester doesn’t cover this one, so it’s sold As-Is / No Return.
