Outstage Unit
The outstage sub circuit is split into two separate units called
outstage-unit, in order to allow for a hierarchical pcb design. With standard
sized eurocard of size 100mm x 220mm each outstage-unit provides board space
for a single heatsink with fan and six copies of the emitter amplifier.
The two outstage-unit sub circuits share the specification with the
outstage sub circuit, except that input and output currents are divided by a
factor of two. The specification is not copied here, because the hierarchical
sub circuit is introduced for the layout and shall not introduce a new logical
component.
