Chokster,

aroundish 100mA steereeoooo (SE) (50mA per channel)

best to use mono approach

if you're Boeing to shunt reg , , 100-150mA programmed current ........ so xformer no less than 350mA per leg

if you're Boeing for series reg , that's it ...... xformer no less than 150mA per leg

Hilarious............

Iím going to be using the Salas LVs, so yes, mono. However while waiting for those Iím dying to try this with what I have, which is nice 24v, 150 mah supply. Sonically, it probably wonít be the best.

Bias it at 1v?
