I can't say that I've seen a ton of Acushnet caps but the ones that I did encounter were always good.I always felt that these were good quality caps in the same league as Dearborn and John E Fast caps.Never saw any of those go bad either.I would just leave them alone and enjoy the radio.

All that brand Ive tested at full working voltage have had no leakage so they may be similar to the red label film Black Beauties of the same era. All my 60's HP gear with those are still perfect. OTOH Acushnet may have had paper construction as well, never took one apart.
Id still test every one or just replace on "principle"....whatever that means
