Ken can probably confirm, but Sony Trinitron tubes are totally unlike/incompatible with all other standard shadow-mask tubes. Even if it is electrically compatible, at the very least you will have significant geometric distortion as Trinitron tubes are flat vertically and only curve horizontally. I would NOT suggest attempting to swap in a Trinitron tube into an arcade chassis.

There are numerous tube swapping web sites.. Use Google and search for "arcade tube swap"  I turned up numerous good links on the first page of results alone.

Again however, you have to ensure many things match before you swap a tube:
1) The pinouts on the tube are identical (need to have good reference books or be able to trace circuit boards)
2) The size/power requirements of the tube are within the same range (e.g. a 27" tube will not work on a 13" or 20" chassis and may not work on a 25")
3) The deflection angle of the tube
4) The impedence and/or dc resitance of the yoke attached to it

Some of the above items are critical safety/immediate circuit damage issues, while others are simply geometric imperfections from minimal to totally unacceptable.  Again, a Trinitron tube is a different beast. I wouldn't waste my time.

can you explain or give example of number 3 and 4? and for number 1, you mean like if the arcade chassis have 10 pins, that mean i have to get a 10 pins monitor? is that right? thanks

Sony picture tubes are completely different internally than other brands of picture tubes. They are NOT compatible at all with any other chassis except another Sony chassis.

Try this tube swap link:
