Lyles); Date: Mon, 8 Apr 2002 10:37:28 -0600; I saw a RCA 1 kW broadcast TX last week that was running new Amperex 4-400's that were graphite plate, without the fins that are on the Eimac/Triton style (that look like 3-500Z plates). The plates w; /archives//html/Amps/2002-04/msg00240.html (7,046 bytes)

They were virtually indestructible, although they didn't put out quite as much as the old Eimac tantalum plate versions. Mike, W1NR; /archives//html/Amps/2002-04/msg00243.html (7,772 bytes)

They work well but they have a bit less vacuum than the metal-anode version. cheers, John - R. L. Measures, a.k.a.

I don't have any experience with Covimag's 4-400 tubes but I do with its bigger brother.

The reason is that graphite tends to hide air molecules during pumping. ? UPS blue/air is a bit better than brown/ground. ?
