TUBES - 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. . My TV-3B/U tube tester doesn’t cover this one, so it’s sold As-Is / No Return. - Additional Pics on Request - . Yours for: $ 50.00 + $10.00 Ship (CONUS) from 92117 - 6x6x6 box - 1-2 lbs. PayPal / USPS MO preferred - Check Accepted, but no ship until clears.
