Default Opinion on those electrolytics needed

I'm in position to buy pretty cheap those caps. How good are they and what are they worth? 01.89 is a production date?

Do something really well. See how much time it takes. It might be a product, a work of art, who knows? Then give it away cheaply, just because you feel that it should not cost so much, even if it took a lot of time and expensive materials to make it. - JC

Those are pretty old. Might use that as a bargaining chip. Buy more than you need, reform them by charging, test them for leakage, and use the good ones, if the price is right. The article "Picking Capacitors" by Jung and Marsh shows how to test them for leakage. The article is on the net some where. Do a search.

Hi Peter,

Sikorel are the highest grade quality electrolytic caps from Siemens for industrial applications, very low ESR, very high ripple current, high temperature, long-life etc.
Should be excellent for audio power amps!

Very expensive when new - I guess one of them was $30 - $40, maybe even somewhat more.

They`re reputed they can be stored 10 years without degradation of specs!

If Id buy older surplus electrolytics than those Sikorel - this ones You have are a bit old though - I wouldn`t pay more than maybe max. 2 - 4 $$ per piece in bigger quantities.
If You plan to buy a big lot maybe You can get a few samples first and to check them out before You decide what they are worth finally.
