As all the electrolytics are the same make then you could consider replacing them all for long term reliability but otherwise I would leave well alone as it sounds great to me as it is.

Notes taken, i should probably screen these cables, yes will change all the caps as i plan to tear it all apart and rebuild it for long term reliability, this amp deserves to be repaired and used.
