CPI 4CX1500B

The 4CX1500B/8660 is a low voltage, high current
tetrode specifically designed for exceptionally low
intermodulation distortion and low grid interception. The low distortion characteristics make
the 4CX1500B/8660 especially suitable for radio
frequency and audio frequency linear amplifier
service.
