Substitutes ................................... 6SG7 6AB7 6AC7
Glass octal type used as rf amplifier in high-frequency, wide-band applications and as a limiter tube in FM equipment. Similar to 6AU6 electrically. Features high transconductance with low grid-plate capacitance.
Suitable for frequencies up to 18 MHz (approx.). Two separate cathode terminals enable the input and output circuits to effectively isolated from each other.
This type is not recommended for high-gain, audio-amplifier applications because undesirable hum may be encountered. Requires octal socket and may be mounted in any position.
