Eimac 7580W / 4CX250R: Offering this from recent estate tube lot - cosmetics indicate either NOS or very, very low hours.
( Taken from Eimac Spec Sheet ):
The 4CX250R/7580W is designed specifically for use in Class AB1 linear amplifiers where shock and/or vibration preclude
the use of non-ruggedized tube types. The 4CX250R/7580W will replace the 4CX250B in equipments where the range of
bias adjustment will tolerate this higher purveyance tube and where tuning range can compensate for the small
differences in input and output capacitances. The 4CX250R/7580W will deliver more output in most linear amplifiers
which presently employ the 4CX250B.
