While I agree that you cannot trust old filters, I have also found that many new filters are also crap. The chinese filters in particular stink. I also put in all new filters in a child's record player I re built two years back. I was periodically using it, so you can't say non use caused it. But, now, the other day, while using it, it had a noticabloe power supply hum that only slowly improved slightly, but, never went away.

I replaced all electrolytics with new IRC filters in one tv. 6 Months later, they failed. What can you trust any more????
