Electrolytic new life expectancy before reforming

[RockinRocket]

Ive have a few F+T sitting going on 4 months and might not get to them until 3 or 4 more months.. Are these going to be fine to use? Id hate to need to reform them as ive never done so.

modern capacitors have no big problems sitting on a shelf for a year,when you install them just power the amp with lower voltage with an autotransformer or light bulb in series and let it on for 30 minutes,than go full voltage.

Thing is this would be a new build. Id want to make sure I didn't muck anything up and have it sit for an amount of time without trying it first.

What's the manufacture date on the caps?

Maybe they were made 1, 2, 3... years ago. The point being that it doesn't really matter - every end user is in the same situation.
