It depends a bit how long they have been lying on the shelf.
What capacity are they? I'm thinking Aleph2...

Sorry that i did not wrote the capacity.
They are 33.000 uF.
How long they were on stock? i do not know. Can't that be read from the codes on the caps?

Hmm...six or eight times 33.000µF/63V would be a good match for a nice class A amp.
Some Rifa caps have a shelf life of 4 years, some 10 years.

I couldn't find the PEA series so I looked at PEH.
There are some threads here at the forum how to power up older caps but the basic rule is slow. 😉

If I read the date code 0001 correctly, they are 4 or 5 years old. If the price is right, I would consider them.
A better reading of the codes on the caps says that they are the PEH169 serie, and not the PEA serie. Sorry.
Any interest for 10 euro each +shipping? I can buy a large lot off them.

Thanks for your info guys!
For what i read and hear from these monsters, i think i buy a large lot off them. If anybody want them too, please mail me, because i have to buy more than i can use (the 10 euro each is only if i buy minimum 64 of them).

Hi,
firm up the postage on lots of 4 and 8. and make sure you cover your packaging costs.
then offer them in trading.
I think they will go fast.
try to find the ripple current and esr spec for them. They could be very good.
I already have my caps but I wish I was still in the market.
