Google search seems to indicate that the SB-240 final was/is an 8873 not
two 3-500s.

The 8873 was used in the conduction cooled amp (the 230 as mentioned
above) which had a front panel *similar* to the one shown below, at
least from a distance.

Also different: the entire back panel was one great big, black,
heatsink.
