4cx7500a
The 4CX7500A is a compact tetrode designed to
be used in VHF power amplifier service. It fea-
tures a type of internal structure which results
in high RF operating efficiency up to 220 MHz. A
dense mesh filament is used which contributes to
the high performance capability of the tube. This
tube is also recommended for use as a VHF TV
linear amplifier.
