Hi Dave
>From Tube Lore a WECO 715B  (which is likely the same as the Raytheon) " 715
Type  Tetrode radar modulators, for airborne use, 356A format slightly
expanded. Has quadruple cathode, single gold-plated grid and screen, single
Mo-Zr plate. 715B Improved version, has bigger heat radiating fins on grid
rods, Fil changed to 26.5 V -at- 2.1A, upper rated to 15kV and 15A."
Kindly use a few as fast as possible. I want to see this VTTC go!
