Default Callins capacitor?

Greetings,

Why do Callins capacitors command such a high premium:

What's so special about them?

What's a good substitute?

Danke,

Nothing. They aren't even new, they are surplus.
As PT Barnum's competitor said, "There's a sucker born every minute."

Just buy new 105F Nichicons from a reliable vendor.

Anything legitimately carrying the Callins name is at least 36 years old.

Is that a non-polar electrolytic? Looks like two regular caps potted.

What use is a 300 uF non-polar 'lytic?

** Yep - no way should you buy even one.

Being epoxy sealed makes no difference to the life span and no small electro lasts 40 years in storage.
The dealer is a scam artist.
Ebay is full of them.
