Do you guys have a source for some of the 160uf 350v caps that are on
this PSU?  I know GPE has the huge 18000uf 25v cap and the other caps
I need for this unit.  Mouser doesn't stock the 160uf caps either and
nothing in the same voltage range.  Digikey doesn't have them either.

Go the next bigger capacitance and/or voltage.  Digikey has a 180uF at
350V and many at 400V.  Check the size to make sure it will fit on the
board.

What capacitor is this?  I didn't see a 160 uF on the Sys9 schematics..

The 160uf on my board is installed at C5... should have looked at the
schematic :)  According to the manual C5 is a 100UF 100v cap... I
think, the manual on IPDB is blurry.

I've never messed with capacitance but I have gone over on voltage
many times.  Thanks for the suggestion!

I am troubleshooting an issue with my Space Shuttle.  I have no active
coils and no voltage at the coils.  I get 26v across the solenoid fuse
on the power supply at F2.  Since this game is unknown to me I'm
capping the entire PSU just in case.

If you get 26 volts across a fuse, the fuse is blown.
