I have a Sprint 2 Power Supply question any help appreciated.I checked
the voltages at the edge connector and at pin 3 and 4 the voltage was
19.5VAC should be 16.5VAC according to the pinout.Also the 25VAC
measured 28.8VAC These voltages were taken prior to the board being
plugged in of course.How exact do these ac voltages need to be are
these readings safe to plug the board in or do they need to be pretty
close to exact.I know some power supplies in some games make the
voltages high to allow for the edge connector connection.Also some
boards have the return line which adjusts the voltage but I dont know
on a Sprint 2 board.If you could let me know what you test them at or
how exact they have to be that would be great....Thanks in
advance....Dave

standard with the ac voltages to be a little high. They are regulated on the
pcb itself.
