Better. High quality electrolytics typically are only "rated" for 5-10,000 hrs, yet if powered on continuously lifespan of even cheapos is substantially prolonged, to the point there is no real set date limit.
In many metrology labs equipment are kept on 24/7, and if that rating were true, 1 year is about 8800 hours, most high end gear would blow electrolytics by the 2nd year; they actually last for decades.
There is a formal way to reform electrolytics if kept is storage for years:
http://www.everyspec.com/MIL-HDBK/MIL-HDBK-1000-1299/MIL-HDBK-1131B_28461/The many methods are similar: slowly ramp up the voltage until it reaches the rated voltage, while current limiting the input to prevent caps from blowing if they are leaking heavily and could overheat; with reforming the leakage current should drop, if not the cap is lost.
There is no formal procedure I know of for incircuit 'reforming' of gear that have linear supplies. For vacuum tube devices, tubes should be removed. Dont' use the variac method on SMPS.
You'll need a variac and an AC ammeter. Find or estimate quiescent current; usually this can be inferred from the manual based on its normal operating power consumption, like if it were as a bench DMM.
Ramp the input voltage from 60V to 120V over 1 hour, watch the current draw of the device. Raise the input voltage 10V/10min.
Keep the current draw, <= quiescent current for each voltage step.
If the current rises over quiescent there maybe a leakly cap that needs more reforming time. Wait another 10 min, or longer, until the current drops.
Once the cap reforms leakage current drops, so that's good feedback that's the culprit, and you can clearly ramp up the voltage to the next level.
If you cannot ramp the input voltage without a rapid current rise, then either the caps are gone or their is a short somewhere.
Once the gear is working, leave it on for a day, then in the future at least turn in on for 1 hour monthly, to insure the caps stay healthy. There is no way for me to verify this is the right length of time, it could be shorter, but as is, its worked empirically for years.
There are other methods and other consideration for the DUT, that may not take kindly to low input voltage. But this 'slow startup' process is a way to insure your eBay gear, that may not have been used in years, has a better chance at working without modding than being torn down for service.
I have always wondered if equipment using tanatalum or aluminium foil with gel dialectrics electrolytics show longer capacitor life with less issues if used regulary, or left unused? For example, I have a new old stock Tektronix 7633 scope. I found one bypass elecrtrolytic just showing signs of weeping and changed it. Had this scope not been unused from new until a few months ago, but had been used say weekly from it manufactire in about 1989, would the caps likely be better or worse?
