    SVT3Pro Bias Setting

    Hello While you are doing bias ajustment, What would be the amp potenciometers possition? What tube trademark it´s right for the driver? What´s the diferent between using12au7A or 12au7wa? What´s better high gain or low gain for HI-FI (without microphonies and noise)?

    Ampeg SVT-3 Pro Tube Gain Question

    In my svt 3, the tube gain control doesn´t change the sound at all? I thinkI´ll change the tubes to try solving it... How i can find the 470 ohm resistor and the potenciometer who limits his current? Have a specific name ind the PCB? some Squematic? PS: excuse my poor english
