    • Anode insulation
    • Anode currents
    • Noise and microphonics
    • Tested at 250 volts with – 2 volts bias to simulate actual conditions in your amp.
  •  Balanced: In addition to the above tests and labelling, we select the units where the anode currents closely match, and record the anode currents and Gm of each triode directly on the box. Also includes a test certificate. Perfect as a phase splitter in your amp to ensure an even drive to the amp output stage.
