4cx300y/8561
The 4CX300Y/8561 is a compact power tetrode
having a maximum plate dissipation rating of 400
watts. It may be operated at maximum ratings to
110 MHz. The ceramic/metal construction and the
internally utilized electrode structure combine to
make the 4CX300Y/8561 especially durable and
free from mechanically induced noise under con-
ditions of severe acceleration caused by shock or
vibration.
