Conversion-Vanguard---> Galaxian

Probably, if your question was more clear.

Your subject: "Conversion-Vanguard---> Galaxian" leads me to
believe that you want to plug a Vanguard board set into a Galaxian
machine. If you really mean Galaxian (not Galaga) and it's a
standard machine, about the only thing that cabinet will easily run
besides Galaxian is Pacman.

In the days before switching power supplies games had line voltage
AC coming in that went to a transformer that output lower AC
voltages. These lower AC voltages went to a power supply that
turned the lower AC voltages into the needed DC voltages (usually
+5 VDC, +12 VDC, and sometimes -5 VDC).

The problem with Galaxians is that the part of the circuit that
turns the low AC voltages into the DC voltages needed is right on
the logic board so when you remove the logic board you remove the
power supply. To run Vanguard out of Galaxians you would also need
to add a power supply. A newer switching supply would work fine
but you still have some pretty extensive control panel mods to do
as Galaxians only has a 2-way joystick and a single fire button.
