Thanks Jafant. I believe the only difference between the 2.4 and 2.4SE model was the use of ClarityCap SA capacitors. I don't have a schematic, but during that time Thiel was purchasing 14uf and 28uf values. They may have been bypassing these with 1uf polystyrene caps. You should be able to confirm this by inspecting the crossover.
Since then we have surpassed SA by two generations-- ESA and now CSA. For that application I suggest CSA/250V or, space permitting, our top CMR/400V model.
