sprague capacitors? Are they worth using anymore?

[drh4683]

So I have a 1942 transoceanic bomber, I completely restored this thing in december of '08, using what was considered "the best" capacitors around. Those sprague orange drops have never failed me, I still can't complain about them, they are great caps. However, today for the first time in months, I decide to power up the TO on 120 VAC. (I usually used the battery pack I bought). To my amazement, the radio was humming terribly while receiving stations. Those dang sprague atom lytics are already smoked!

Either I got a bad supply of them, or the quality control has slipped big time on those. They were new caps when I put them in with 07 date codes I believe, so they were only 1 year old when they got installed. So basically, 3 years later and they are junk. I'm now considering the use of Nichicon lytics in place of the spragues. Anyone else use atoms recently only to be let down like I did? I guess the biggest annoyance here is that I put so much time and effort into recapping it neatly and correctly, yet it all has to get ripped apart again and done over.
