    Ok once the math is done and you have your mA value,( just for an example lets say its 36mA) on the dsl with the three pin test points, is it balanced at 36mA or 72 mA ( center to left pin, and center to right pin)since it a pair of tubes per side?

    The DSL100H has two tubes on each side of the push-pull power amplifier. The left pin measures on side and right pin the other. You should measure about 72mV(mA), which would be about 36mV(mA) per tube, at each pin to center pin.
