| cpi | 4CX250R/7580W cpi|4cW50,000J 4CX250R/7580W 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 and it will operate with maximum rated plate and screen voltage applied in euipments where shock and/or vibration is experienced. chaRacteRistics Plate Dissipation (Max.)
