I should note that in checking my Major Havoc schematics (which I also have
at work ;-) the circuit has no multipliers. Op amps are used to do all the
scaling, and there is not correction signal passing between the different
axes. Perhaps the Ampliphone monitor had better orthogonality and didn't need
the correction circuit?
People have complained about Star Wars/MH/Quantum not looking quite right on
WG because they tend to bow, although the effect has never been that
pronounced on the WG in my Tempest.
Might be an interesting question for Greg Woodcock
