    Just reviewing the circuit - I obviously missed a DC blocking cap. I'm fairly sure it went between the junction of the 470K and 510K and the 6SL7 grid (pin4) on Sheet 1.

    Cheers,
    Ian

    AMPEG ET-1B Restoration

    Just completed a restoration of a 1968 Ampeg ET1-B
    Schematics around the web were unreadable resolution so did a circuit trace myself.

    For you possible interest.

    Cheers,
    Ian
