  1. 6L6GB Sylvania Black Plate Beam Power Amplifier Matched Pair (2) (NOS)

    6L6GB Sylvania Black Plate Beam Power Amplifier Matched Pair (2) (NOS)

    $99.91

    The 6L6GB is a beam pentode designed primarily for use in audio-frequency power amplifier applications where relatively large power outputs are required.

    Note: These are not as durable as 6L6GC types so it's not advised to use in amps where the plate voltage is over 410V

  2. 6L6WGB Tung-Sol JAN-CTL / 5881 Electron Tube Matched Pair (2) (NOS/NIB)

    6L6WGB Tung-Sol JAN-CTL / 5881 Electron Tube Matched Pair (2) (NOS/NIB)

    $297.91

    The 6L6WGB / 5881 is the electrical equivalent to types 6L6 and 6L6GC except that the plate and screen dissipation ratings have been increased approximately 20 percent. It embodies a complete mechanical redesign which results in greater resistance to shock and vibration. The use of treated grids and anode greatly increases its overload capabilities and thereby provides desirable improvement in continuity of service. The addition of a low-loss barrier type base will provide obvious advantages in certain applications.
