There is no such tube as a 4CX3000A7.

Subject: [AMPS] 4CX3000A7 GG ?
I read a description of a tetrode linear amp that had both grids =
grounded to the chassis and the drive applied to the cathode through a =
filament choke. Could this grounded grid application be applied to a =
4CX3000A7? Would it work similar to a grounded grid 3CX300A7, ie. high =
drive power requirement etc.
73,
