and one more question - which way to solder it? :) as I know they got sides - but there are no strip or something on new one to know that

by

if there isnt a negative indicator, like the strip, its unpolarized meaning it doesnt matter which way it goes in.

Now I've done this and I'm SCARED to connect it to socket and switch on - as I still remember what was happened when that old capacitor blew up :(

I've also soldered that capacitor in random polarity.

I also ripped off circle pad on (around capacitors one of the pins) right side of capacitor (next to the scratch) and soldered it to upper path - which I'm not sure if should it be separated or it is part of the path to capacitors leg

I really can't tell where you are trying to use this. But here's an explanation of VAC

The voltage rating is a function of a switch's ability to suppress the internal arc that occurs when a switch's contacts open. ... So, in the example below the maximum amp rating for this switch at 250 volts AC (VAC) is 10 amps; the maximum amp rating at 125 volts AC for the same switch is 15 amps.

Here;'s where you can get parts and advice on replacing the caps on this machine:
