TT 12AX7 / ECC83 Classic V1

TT Selection: Balanced
Both systems with balanced gain

The TT12AX7 impresses with its fine and detailed reproduction of the highs, which is maintained even at high amplification levels. Due to a higher H3 part, the TT12AX7 sounds significantly cleaner than many other 12AX7/ECC83 tubes, which makes the bass range appear much tighter. We therefore especially recommend this tube for styles such as clean, crunch, and metal, where high amplification and clear transparency are required.

Electrical Characteristics

Heater voltage (Uf): 6.3V or 12.6V
Heater current (If): 300mA at 6.3V, 150mA at 12.6V
Anode voltage (Ua): Maximum 300V
Grid voltages (Ug1): -2V (typical)
Grid voltages: -50V to 0V
Anode current (Ia): 1.2mA (typical)
Anode power dissipation: Maximum 1W per triode
Anode resistance (ra): 62.5kΩ
Amplification factor (μ): 100
Transconductance (S): 1.6mA/V
Input capacitance (Cin): 1.6pF
Output capacitance (Cout): 1.6pF

Mechanical Characteristics

Socket: B9A (Noval)
Number of pins: 9

Pin Configuration

1 Anode (Triode 1)
2 Grid (Triode 1)
3 Cathode (Triode 1)
4 Heater (f)
5 Heater (f)
6 Anode (Triode 2)
7 Grid (Triode 2)
8 Cathode (Triode 2)
9 Center Heater (f)

Application Notes

Heater operation: The tube can be operated with 6.3V or 12.6V, depending on the circuit design.
Grid resistors: It is recommended to use grid resistors of at least 1MΩ to ensure stable functionality.
Coupling capacitors: Capacitors with low capacitance (typically 0.1µF) are recommended to minimize high-frequency interference.
