I Built and Used My First Incandescent Bulb Current-Limiter

I = C.dv/dt
if C = 2000uF and the cap charges to 30V in 0.5 second, I = 120mA.
To " bottom out " a woofer a takes several amps.
Sure. But lets say that the power supply comes up to full voltage in 1/4
cycle, which is perhaps closer to the truth.

The mid point voltage of a single supply output stage rise *independantly*.
Like I posted, it typically takes a second or two.
