TUBES - 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. - Additional Pics on Request - Yours for: $ 40.00 + $10.00 Ship (CONUS) from 92117 - 6x6x6 box - 1-2 lbs. PayPal / USPS MO preferred - Check Accepted, but no ship until clears.
