The amplifier is deliverable with different tubes, PX4 is standard and sounds best, but we also can deliver with other types for higher gain and/or lower output impedance and/or lower noise and microphonics.

Technical specifications:

Input impedance:

100k

Gain:

5 times (+14 dB)

Output impedance:

600 Ohms

Max output:

20 Vrms with 30 mA

Frequency range:

10 Hz - 120 kHz, zero feedback

Distortion THD% at 1 kHz:
