Re: Hunts capacitors
Yes. If it is a decoupler make sure it is fitted in the same physical place as the original. It will probably be smaller but no problem. J.

Re: Hunts capacitors
Any capacitor rated at 400V or higher that will fit will be OK.
Of course, it's best to use on of the same type (e.g. film) It would be worth checking for any other Hunts capacitors that are present as they are usually best replaced on sight.

Re: Hunts capacitors
I think we all know that Hunts made some of the best electrolytic capacitors that there are - probably more by luck than design, though.
We need to try to remember to be specific when advising on things like this to save on possible confusion. |

Re: Hunts capacitors
Hunts were not a particularly poor manufacturer. It's just that the technology used to make consumer grade capacitors in the 1940s and 50s has a finite life - these things are over 60 years old now. British restorers also encounter a disproportionate number of bad Hunts caps simply because Hunts supplied most of the UK manufacturers.

Re: Hunts capacitors
Indeed, youtube's american restorer Shango066 has choice words to say about american-made vintage capacitors from Mallory, Sprague, Cornell Dubilier, Aerovox and a thousand others. I doubt he's changed many Hunts over there!

Re: Hunts capacitors
My Eddystone only had one "Mouldseal", which I replaced years ago, but the "Dipseal" ones are all still functioning.
