Restoring Sherwood S-5500 capacitors inquiry

Hi there!
I've got this amp last year in pretty good shape but it needed a re-cap, etc.
I just decided to go back into this project and while examing the components I need, I found that one of the electrolytic capcitors is functioning in a negative current.
Maybe it is a silly question, but I would like to know, do I need a special type of capacitors to replace that multi-value cap? I'm attaching a pic of the original cap, and the portion of the schematics that related to my question.
I'm not an expert, but as far as I know you should not wire positive terminals of electrolytic cap to the ground, but when looking at the schematics it looks like the negative leads are connected to the circuit components and the positive leads to the ground.
If anyone can clarify it, that will be great.

I've replaced multi-cap cans that had a common positive or common negative. Can't remember one can having a mix of positive and negative commons inside, but could have forgotten. Have restored a Sherwood in the 5XXXX series, but it might not have been a 5500.

Edit: Oops, upon closer inspection of the can photo, it appears the can might just be a common positive can.

Thank you @BmWr75 !
Yes - on the original can it is common positive, but I just wonder, when using regular electrolytic caps, can I solder their Positives leads to the ground, and use their negative leads as it shows on the schematics? I hope my question is clear
