[Amps] Eimac tube designators

[PLoret1648@aol.com]

Someone had listed what the designators mean in Eimac power grid tubes, and I 
can't find it. Maybe more coffee..... Anyway, a 4cx1500bm/y-757. I called 
Eimac for info, and they sent me the paperwork for the 4cx1500b, saying it 
was nearly identical. Any help greatly appreciated.
