4CX1500B 8660
The
4CX1500B / 8660 vacuum tube 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.
