Hi there,
 
I built two tangent tread power supplies some years ago and used them for my jisbos buffers.
 
I'd like to know if they can be powered from the +/- 24V AUX-output of a B&O
Icepower module?

Maybe.
 
First, the standard TREAD design used a bridge rectifier, which looks like two diodes in series to a DC source. This means you're going to be feeding the regulator about 22.6V, so the regulator needs to be set to about 20V or below in order to maintain regulation.
 
Second, your +/-24 suggests that your power source is a symmetric dual-output supply. Whether you can run the negative side into the lower half of a totem-pole-stacked TREAD pair depends on whether the power source is floating or not. A ground-referenced power supply won't work in this situation; you'd need to have a true negative regulator to make it work.
 
You really need to know what you're doing before you go throwing random power components together.
