Biasing the JCM2000 amps

Here are the official Marshall biasing instructions for the JCM2000 amps. I myself find the official bias settings too high and muddy sounding. I often bias the TSL amps to somewhat lower settings, often around 35mA each tube (70mV on bias connector) instead of the recommended 45mA. As this is very personal, I recommend trying this out for yourself.
