I also have a copy of the schematics to this monitor. The biggest change was
the doubling up of the output transistor. Each channel now has four power
transistors instead of two.

They also increased the +/- voltages to that of those of Sega, which would lead
to a faster slew rate. Other than those changes it is very similar to the old
WG monitor. The high voltage section is slightly modified to run off of one
rail of the +/- 50v, as opposed to across both rails of the +/- 25v supply.

Basically you'd have to go through and change all the (affected) capacitors to
higher voltage ratings, and double up the output transistors to account for the
extra power dissipation (which is a *much* better way of doing it than adding a
big fan - a la Sega)
