Sikorel caps break-in time.

[beppe61]

Dear Sirs,

I have just replaced in my amp two old filter caps with two 15.000uF/100 V Siemens Sikorel (B41570 series-105°C).
I have two question for people with knowledge on this kind of components:
1) the production date is 05/93. I bought them as new old stock.
Are they expired in some way? Are they too old ?
2) how long will the break-in process take ?

Any other suggestion and information would be very welcome and appreciated.

Kind regards,

beppe
