Hi, Anyone out there have specifications on a water-cooled tube made for Amplifier Research, part # 1001960-101? The base is similar to the 4CX250 series. Any information would be appreciated 73, George K8BRW -- FAQ on WWW: http://www.contesting.com/FAQ/amps Submissions: amps@contesting.com Administrative requests: amps-REQUEST@contesting.com Problems: owner-amps@contesting.com
