4cx3500a
The 4CX3500A 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. This
tube is also recommended for use as a VHF TV
linear amplifier. for use as a Class C radio frequen-
cy power amplifier and plate-modulated, radio
frequency power amplifier.
