Test AC ripple voltage to see if it's doing its job.
Might also test capacitance if you have an accurate meter that measures 6800uF.

Hook your capacitor up to rated voltage momentarily and measure in-rush current. From there, you can calculate impedance. With impedance, you can calculate capacitance.
Where capacitance= 1 divided by(2*pi*Frequency*Impedance).
Keep in mind, these NVRAM upgrades do require you to run your board with a bit more juice than normal. Especially on the older boards.

Then you probably won't want to add a JOUST 2 to your collection. LOL
I'm no repair wiz, but I did the recap/rebuild kit on a Williams PS and was missing a voltage. If you look at the schematic for a particular voltage, there aren't a ton of components. I checked continuity through the circuit and found a break from the top to bottom of a hole at the biggest radial cap on the board. Pulled it, replaced it with another so I had so lead on top, soldered from top also, bada bing. It's gotta be something simple.
I had a similar issue when I rebuilt my cocktail PS. Although mine never flickered. I just didn't come on.
I made a few mi$take$ along the way. But the main one is to make sure to solder the top and bottom of all components that you replace.
The main problem though was the new transistor on the heat sink that was bad. I re-used the old one and I had the 5V again.
