I'm looking at buying a pair of GU74-B's to have on hand as spares for my Titan 425. Has anyone out there replaced the 3cx800A7's with GU74-B's?? Greg -- Greg Chartrand - W7MY Richland, WA. DN-06IF W

The GU-74B's are supposedly the same as the 4CX-800, not the 3CX-800A7 73 Roger (K8RI) 73 Roger (K8RI _______________________________________________ Amps mailing list Amps@contesting.com http://list

Its a rebranded 600W GU-74B with a magical free 200W of extra Pd to con the ham market. Its also a pretty non linear tube unless the ZSAC is cranked up close to Class A. Great shack heater. Carl KM1H

Hi Roger, Eimac 4CX800 never existed. American amps and other were built for some time by using NOS Russian GU74b, probably dropped from a military storage shelf 73 Peter the So the Eimac the America

4CX800 was a dream of George Badger and Bob Alprin. I summise that they were trying to get the Svetlana tubes onto the market and use a number that was more recciginazable thatn Gu74b. It never did t

Hi Arno, I would prefer you send me a photo of a 4CX800A7. Neither Alpha nor Acom amps have 4CX800 tubes built in, all are GU74b. I can design you a datasheet with whatever you like to include within
