Does anyone know what the value of the BIG caps in a Midway PS part number 80-901?

The game is Midway GunFight, the manual doesn't include PS schematics. Thanks I'll order them.
Gun Fight has a totally different power supply than a Tapper. Those above mentioned caps are way too big for the Gun Fight.
According to the schematics...it uses...
2000uf25V axial
1000uf35V axial
20000uf16V axial
6000uf35V axial
470uf16V
10uf25V
10uf25V (optional)
A couple of those are impossible to find values...so you have to use the next available size...Example: 2000uf is no longer made...substitute a 2200uf.

Thanks, one thing I noticed was that the 2 rec diodes by the plug have burnt areas around the base and heat up alot? I am guess that's not normal. the Diode # is 1n5624.
I was looking at that also. However, the power supply he mentioned is a 80-901 and the power supply in the manual is a 80-904. There is a note in the manual that two different power supplier were used in the game but there is only one schematic listed. WTF?
