Could someone test, how accurately A-136 does the half and full wave 
rectifying at audio rate? On paper it looks capable, although some 
precision knob twisting seems to be needed...

+L and -L (level controls) should be at zero.

A (amplification control for original signal) at 5 (twelve o'clock).

+A (amplification control for positive signal component above the 
positive clipping level) at 3.5 or 6.5 depending the desired type of 
rectifying.

-A (amplification control for negative signal component below the 
negative clipping level) at 3.5 or 6.5 depending the desired type of 
rectifying.
