 EIMAC 4X150A/7034 have same specifications as a 4CX250B. The characteristic curves are identical. The only real difference is that the insulator between plate and screen ring is glass and not ceramic. So it would probably be best to give them a little extra cooling if you are pushing them. There are several different 4X150A tubes. Not all are 7034. 73 Bill wa4lav ________________________________________ From: Amps [amps-bounces@contesting.com] on behalf of RMorris [robrk@nidhog.net] Sent: Saturday, December 27, 2014 5:12 PM To: qrv@kd4e.com Cc: amps@contesting.com Subject: Re: [Amps] Power from Pair of Eimac 4 x 150 a / 7034?

Build it so, later, you can plug in 4x250's or 350's. _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps
