Josh,
Get a stable 10amp Variac. After soldering in your new cap AND double
and triple check your connections and polarity!
Replace any indirect rectifier (like a 5AR4/GZ34) with a direct
rectifier (like a 5Y3GT). Plug all tubes in & have speakers connected.
Volume at zero. No inputs.
Start at 60 volts VAC, for one-two hours. Check for anything unusual
(smoke, smells, etc). If all okay after 2 hours, ramp the Variac up to
80 volts (another 1-2 hours). Continue this trend until you reach 118
volts.
I find slowly ramped-up or formed electrolytic caps last a lot longer
than ones which aren't.
