Sprague atom's are quite renowned themselves.
I never use electrolytics for signal coupling, but for power supplies and de-coupling I use Sprague atom's frequently. They are a very good quality electrolytic capacitor.
Very good in their day, but that was quite a while ago and their day has been over for some years now. A new cap from almost any reputable maker will be better in every way than a 20+ year old electrolytic.
Their old slogan- "Don't be vague, ask for Sprague!"
