ShuGuang Sounds Of Nature 12AT7-T 12AT7 ECC81 Vacuum Tube Triode Electron Tubes
1. Description:
Shuguan 12AT7-T can replace 12AT7, has somewhat lower voltage gain than the 12AX7, but higher transconductance and plate current, which makes it suitable for high frequency applications.
Originally the tube was intended for operation in VHF circuits,
such as TV sets and FM tuners, as an oscillator/frequency
converter, but it also found wide use in audio as a driver and
phase-inverter in vacuum tube push-pull amplifier circuits.
The tube has a center-tapped filament so it can be used in either
6.3V 300mA or 12.6V 150mA heater circuits.
